Clubhead speed and carry+roll

I've had monitors tell me my driver swing speed is between 104 and 112 mph, depending on the monitor and the day and how much I go after it.  I've had the same experience, where those monitors tell me I'm carrying it ~280s and rolling out past 300 on all the straight ones.  I think that's a little bit inflated, but not much.  On flat fairways that aren't overly hard I tend to get carry+roll in the 280s on my solid, straight drives on standard SoCal warm, dryish days, but my best couple drives each round will end up past 300 even without excessive roll or downhills or anything.  Note of course that my true mean isn't over 280, since I don't hit every drive solid and straight!  

 

But the point remains that you definitely don't need swing speed over 120mph to get carry+roll of 300 yards.  I'd guess that that's 300 yards of carry.  I'd believe that, since I know for sure I've never carried a drive anywhere near 300 yards and that my swing speed is significantly below 120mph.  Maybe you need swing speed of ~110mph with center contact and good smash factor to get carry+roll of 300 yards on a flat fairway of average hardness and roll when it's not too cold or wet?

http://www.iseekgolf.com/clubfittingandrepairs/7313-angle-of-attack-its-role-in-fitting  givers you a carry of 274 at 105mph with a perfect strike (good luck with that) which matches what I have seen elsewhere. 25 yards of roll isn't unreasonable on a lot of course while on some others ones the your roll out will be more like 10 yards. You could also tweak your swing for more roll less carry and squeak out a few more yards on certain courses. So in theory yeah you can hit 300 with a 105mph club speed. Reality is that if you getting much above 270 on a regular basis you are doing good.   Personally I think they set all the launch monitors to 5k ft so everyone hits the ball just a bit farther.  I am also convinced that all of the practice putting greens slope to the hole at my local store.

 

 

 

105 mph, +5 angle of attack gives you 274 yds of carry with a 10 degree driver, that's correct.

add to that a spin rate of only 2070 and a firm FW, and you're likely to pass 30 yds of roll.

ergo, +300 yds total distance.

Question...

 

I am wondering about my driver distance. I have 11.5*... dunno my swing speed (probably 75) ... currently I am ranging in at about 189 - 195.. Is that accurate?

The chart is about right (at least for distances) for maximum carry. For maximum distance (ie. carry plus roll) you tend to use a slightly lower loft driver. I wouldn't be shocked to learn that in TX you hit your driver about 160 yards carry and get 30+ yards of roll. Teebox elevation can also be good for a half dozen yards.

Ouch.... man I just got a driver for Xmas... Looks like I need to either speed up my club head speed or get a high loft club!! *Ouch*

Weather could have an impact as well...or for an indoor monitor, a computer weather setting.

Roll is unreliable. In the summer i have hit my 3 wood 300 yards before, when i purposely hit a low stinger type shot. But in the spring, that thing is 50 yards back. 

 

I rather get as much carry as possible, i know a few guys who gain a good 30 yards between spring and summer on there drives, because they hit the ball lower

All the info and charts above seem reasonable to me. My info from testing drivers the other day (typical SoCal winter day, sixty degrees, no wind): 106-107 club head speed, 160 ball speed, -4 attack, 9 launch, 2200-2800 spin ... And the best shot I recorded was 268 carry and roll out to 280-something.

(Pretty obvious that my 'problem' is in the attack angle category :))

It's all about impact. I have a highish swing speed {115-117) but i make terrible contact, smash factor only around 1.35... Also, most of the fairways near me give zero roll. A lot of times my ball will be a few feet behind the plug mark where it landed.
