OK, that was short lived LOL. A guy I work with wanted my SUMO2. He had the driver I really wanted, I know I'm a flake and fickle.....

Anyway, I traded my coworker for his FTi.

I wonder how long I'll be happy with this one LOL...

I think it was a good trade for you. Never been a big fan of the Sumo. Report back with results of your newly acquired toy.

He is looking for distance. I just want to hit the fairway. I did have to throw in my old Odyssey putter but I figure it was only worth about $60 or $75 so I'm happy.....very happy.

I guess I just killed this thread LOL.

The burner has a better MOI rating than the SQ and is longer.

P3R3,

No, the Burner does not have a higher MOI rating. The Burner is at 5000 while the Sumo2 is at 5300. Don't equate TaylorMade's eMOI to MOI. That eMOI thing is marketing crap someone at TaylorMade thought up to make their clubs sound better than they really are. They were hoping people would confuse eMOI with MOI and you are proof that it has happened. Scott

P3R3,

There is very little difference between 5000 and 5300. Being an engineer I've had to calculate MOI before.

P3R3,

Oh my, the Engineer card.... The difference is that the Sumo2 has a 6 percent higher MOI. As an Engineer, I assume you realize that 6 percent is a significant difference. Also, you said that the Burner had a higher MOI which was completely inaccurate. As an Engineer, you should appreciate accuracy. Scott

P3R3,

6% is significant in some places and rather insigninficant in others, particularly when all the numbers may be somewhat inflated.

With MOI, even 20% can be seen as insignificant. It depends on the player and other factors. For example, I tend to hit the center of the clubface, so. 6% is definitely insignificant to me.

iacas,

If 6 percent is insiginificant in regards to driver head MOI, why would both Callaway and Nike, who have near 5000 MOI conventional drivers, come out with square drivers? Also, both the Sumo2 and FT-i are noticeably better on off center hits compared to their more conventional drivers. So, for what MOI is important for, 6 percent is not insignificant.

If you hit the center of the face everytime all the time, then your better than most PGA Tour players....

Because, for some people, 6% is significant. Did you not bother to read what I wrote?

Also, both the Sumo2 and FT-i are noticeably better on off center hits compared to their more conventional drivers.

They're also shorter, louder, and more awkward to look at.

So, for what MOI is important for, 6 percent is not insignificant.

Apparently you did NOT read what I wrote.

If you hit the center of the face everytime all the time, then your better than most PGA Tour players....

Uhhhh, no. No I'm not better, and no your statement is not true.

But let me try again so you can understand: I rarely mis-hit my driver so badly that 6% will matter much, and in fact it might hinder me when I try to shape the ball a little as I like to do. Read my Titleist 907 driver review.

Winder/Scott:

It is insignificant. Here's what Frank Thomas, former USGA Technical Director, has to say:

"Originally, the USGA proposed a standard on MOI of 4,800 gm. cm ² (see http://www.franklygolf.com/Speak/moi.asp for a simple explanation of MOI), but soon modified this after the manufacturers suggested that it was inappropriate. The USGA explained its quick change of mind by saying that it was based on input from the manufacturers, and that going from 4,800 gm. cm ² to 6,000 gm. cm ² “doesn’t mean anything in real terms.” Studies have shown that the USGA’s statement is correct, that this change doesn’t mean much in real terms. The obvious question, then, is, If this change doesn’t mean anything, would a violation of the new limit mean anything? And if not, then why set the limit?

"When drivers increased in size into the 400-460 cc range, they went from MOIs of about 2,000 gm cm² to 4,000 gm cm². This was a real change that improved forgiveness and led to a significant improvement in performance on mis-hits. But there is a phenomenon known as the law of diminishing returns; every incremental increase does not lead to an equivalent increase in performance. Most of the 400cc to 460 cc drivers perform very well, and are only slightly less forgiving than the newest and latest Square Drivers with MOIs approaching the 5,500 gm cm² range. The difference in performance is simply not significant; this is a text book example of diminishing returns."

Then again, you probably won't believe him either because he's an "engineer." Give it up.

P3R3,

I dont read the numbers, I just reep the results

ANYWHO here is the equation for moment of inertia. In order to increase the MOI by .06 the MASS must be increased by .06 or the distance to axis of rotation must be increased by .02 Since increasing the club head weight results in slower swing speed and increasing the clubhead volume is not allowed by USGA rules the clubhead must be "stretched" usually resulting in a smaller area of inpact. Sorry for all the math.

Go ahead and square 0.02 and you won't get 0.06%, that's for sure. More like 0.0004. You mean to say about 0.25 (~0.245).

A small number, any way you look at it. Frank Thomas knows his stuff.

I`m sorry for shaking alive a old thread, but I really get nervous while reading here. People think the Sumo2 is bad? I`ve just ordered it from Canada, this being my first driver.
I`m one of those who`s going down the handicap spiral now. With a 7 wood, I hit 220 metres from the FW now. And with 3W from the tee, I shoot about 220-250 metres.

So now I`ve decided to invest in a driver, and the SUMO2 was appealing. Have I made a big mistake?

I have made one hole in one this far. While you are reading this, I am most likely out on the tee trying to sink another one


Posted
I, and many others, just don't like the asthetics and sound they make. Most people who hit them seem to hit them long and fairly straight.

My swing is horrible right now, but I golfed with a guy who's swing makes mine look like a pro, and he was hitting the SUMO2. That guy's misses were way better than my misses.

The thing just looks and feels too weird for me. It's got a certain "Jack from Caddyshack II" thing going on that I just can't seem to get over.

Posted
Ok. Thanks for the info. I`m still unsure. I wanted a driver, and I chose this one. I`m afraid I won`t drive as far as I could with other drivers. May that be a problem?

Ditto Ditto and Ditto!

I love this club! I bought it wholesale and I'm waiting anxiously for its arrival. The sound it makes, although different, didn't seem all that loud to me. Instead of a "tink" sound of titanium meeting Surlyn, it makes more of a Poooowww sound like a hollow empty soda can being stomped on.

I'm hitting my SQ2 3 Wood almost 300 yards. I cannot WAIT to see how far I hit it with this Sumo2.

    • Nah, man. People have been testing clubs like this for decades at this point. Even 35 years. @M2R, are you AskGolfNut? If you're not, you seem to have fully bought into the cult or something. So many links to so many videos… Here's an issue, too: - A drop of 0.06 is a drop with a 90 MPH 7I having a ball speed of 117 and dropping it to 111.6, which is going to be nearly 15 yards, which is far more than what a "3% distance loss" indicates (and is even more than a 4.6% distance loss). - You're okay using a percentage with small numbers and saying "they're close" and "1.3 to 1.24 is only 4.6%," but then you excuse the massive 53% difference that going from 3% to 4.6% represents. That's a hell of an error! - That guy in the Elite video is swinging his 7I at 70 MPH. C'mon. My 5' tall daughter swings hers faster than that.
    • Yea but that is sort of my quandary, I sometimes see posts where people causally say this club is more forgiving, a little more forgiving, less forgiving, ad nauseum. But what the heck are they really quantifying? The proclamation of something as fact is not authoritative, even less so as I don't know what the basis for that statement is. For my entire golfing experience, I thought of forgiveness as how much distance front to back is lost hitting the face in non-optimal locations. Anything right or left is on me and delivery issues. But I also have to clarify that my experience is only with irons, I never got to the point of having any confidence or consistency with anything longer. I feel that is rather the point, as much as possible, to quantify the losses by trying to eliminate all the variables except the one you want to investigate. Or, I feel like we agree. Compared to the variables introduced by a golfer's delivery and the variables introduced by lie conditions, the losses from missing the optimal strike location might be so small as to almost be noise over a larger area than a pea.  In which case it seems that your objection is that the 0-3% area is being depicted as too large. Which I will address below. For statements that is absurd and true 100% sweet spot is tiny for all clubs. You will need to provide some objective data to back that up and also define what true 100% sweet spot is. If you mean the area where there are 0 losses, then yes. While true, I do not feel like a not practical or useful definition for what I would like to know. For strikes on irons away from the optimal location "in measurable and quantifiable results how many yards, or feet, does that translate into?"   In my opinion it ok to be dubious but I feel like we need people attempting this sort of data driven investigation. Even if they are wrong in some things at least they are moving the discussion forward. And he has been changing the maps and the way data is interpreted along the way. So, he admits to some of the ideas he started with as being wrong. It is not like we all have not been in that situation 😄 And in any case to proceed forward I feel will require supporting or refuting data. To which as I stated above, I do not have any experience in drivers so I cannot comment on that. But I would like to comment on irons as far as these heat maps. In a video by Elite Performance Golf Studios - The TRUTH About Forgiveness! Game Improvement vs Blade vs Players Distance SLOW SWING SPEED! and going back to ~12:50 will show the reference data for the Pro 241. I can use that to check AskGolfNut's heat map for the Pro 241: a 16mm heel, 5mm low produced a loss of efficiency from 1.3 down to 1.24 or ~4.6%. Looking at AskGolfNut's heatmap it predicts a loss of 3%. Is that good or bad? I do not know but given the possible variations I am going to say it is ok. That location is very close to where the head map goes to 4%, these are very small numbers, and rounding could be playing some part. But for sure I am going to say it is not absurd. Looking at one data point is absurd, but I am not going to spend time on more because IME people who are interested will do their own research and those not interested cannot be persuaded by any amount of data. However, the overall conclusion that I got from that video was that between the three clubs there is a difference in distance forgiveness, but it is not very much. Without some robot testing or something similar the human element in the testing makes it difficult to say is it 1 yard, or 2, or 3?
