How much shaft lean is too much

18 posts in this topic

I was looking at a table That Lucius Wooding posted about tour players stats and it showed Nearly all clubs had a maximum height of 30 yards....give or take 1 or 2 . So 30 yards for a pitching wedge.....that seems incredibly low. So the pros are putting the ball back and using alot of forward shaft lean to get such a low number. My question is how much shaft lean is too much. And what are the dangers of too much?

It has a lot to do with clubhead speed, and spin loft. Basically, more spin = higher launch because backspin will cause the ball to rise. Its why a fastball is thrown with backspin, to keep it from dropping, making it a straighter pitch. But also, ball speed effects that as well, more clubhead speed, higher the golf ball. Its just something about how golf is, that the decrease in clubhead speed for each iron and the increase in backspin keep the ball near the same weight.

With a wedge, the ball launches at about 65% face and 35% path, and the path is -6° or so , and the delivered loft is often only 35° or so (shaft lean), so you can get a ball coming off pretty low.

I've said several times most people don't realize:

a) How high a PGA Tour player hits his long irons.

b) How low a PGA Tour player hits his short irons.

They all tend to max out at about 30 yards, though. With the driver it's obviously much farther down-range than with a wedge.

I don't know about putting the ball back in their stances (farther than center anyways, but you'd be hard pressed to find a PGA pro without forward leaning shaft. At least on irons. Iacas: Do you have some data from amateurs (scratch) compared to pros on this? Launch angle consistency and peak height through the bag.

Yes. It's what you'd expect: the higher the handicap, the less the consistency and the higher the launch angle (due to more delivered loft). Peak height tends to be too low with long irons and too high with short irons.

Would you ever say to a student "you've got too much shaft lean and this problem is happening because of it?"

Yes, there are students that have too much shaft lean at impact (such as me), and tends to hit the long irons too low to have optimal trajectory. It's worse when the AoA is really shallow with too much shaft lean, because you'll often have too low spin and low launch to have sufficient carry.

Yes, Rupert. I've said it before quite a few times. Ideal is the shaft lining up *just* after impact. I'll take a guy lining it up later over a guy who lines it up too soon, but both are sub-optimal.

iacis, Can you clarify what you mean by "lining up" the shaft? Is this the same concept that Manzella is advocating in his Ideas About The Release.........well timed release.......rapidly moving the left wrist to a cupped position through impact interval?

I think 'lining up the shaft' is relating to your lead shoulder down to the clubhead. It should occur just after impact meaning that the clubhead should bottom out just after you hit the ball.

At least that's what I got from his statement and agree with it.

Example of to much shaft lean.  This is from my lesson yesterday the idea was for me to be able to over do it a bit to get the feel

as I am still flipping a little..  The drill he had me do to get here was using a ping pong paddle and and only see one side during the swing

so I could get the fell of what my hands should be doing.

I don't know what Brian's current flavor of the week is.

I'm talking about the shaft lining up with the lead arm (or the proxy, in the case of Lee Westwood and his ilk) at or just after impact, not before. The picture below your post (and quoted here) is a good example of too much shaft lean - the shaft still hasn't lined up and won't until well after impact.

It's fine in a drill/practice, but if this was a real swing, way too much.

I think by now that my answers would be pretty obvious, no?

And shaft lean matters less with a driver. So only the last one's one I'd change, and who knows - he might have been hitting a bit of a different kind of tee shot there. + AoA without increasing delivered loft a ton, though. Ball go far.

I am truly trying to get the picture.  I think I understand what you are saying but ... Can  you post a pic of what you fell is perfect forward shaft lean

or perfect impact position.

You can probably find somewhat ideal positions with one club, one ball position and one player, but there are too individual differences to nail it in one general picture. The driver is especially difficult, as you don't need the same kind of position as with irons. Look at the impact position of various good players and you'll soon enough see what it looks like. This isn't science you put down to a single reference point.

A shaft inline with the lead arm or just behind it (i.e. will line up right after the golf ball).

And the above does nothing to state that there aren't cases when you'd want a little more shaft lean due to what it can do the impact dynamics.

      Actually, they mentioned today that it's an environmental requirement imposed by the government; local, state or federal, they weren't sure.
    • Steel vs Graphite generic question
      Spin is OK though? I could be flipping a little but I may need work on Key #3 to get that launch down to where it needs to be... Because I SHOULD be carrying my 7-iron 160-165 with that speed.  Maybe the motor is fine (the shaft), just need to work on in-line impact more...
    • Finding Value in The Used Club Market
      I'm liking this:   That makes a lot of sense.  Local Retailers may be getting some of the last years models dumped on them when the new clubs start cycling through.  I was thinking about doing the demo days thing to get a taste of what is out there.  The R7 limited and R11 Taylormade Drivers were good to me.  I think a X2 hot/Big Bertha/etc/ect would probably be more forgiving.  Still, I look at the clubs of old... the Cleveland Launcher Comp / Callaway Hawkeye and think: "If I can buy that club for $20... and I can buy newer (used) for $50-$100... hmmm.  Spinning the wheels.  Thanks for the advice though I really appreciate it. If anyone has a Driver / had a Driver they loved from (2009-2014) let me know about it!  What did you like/didn't like?
    • My ex-home courses closing, changing - proofs that golf is in decline
      I just found out that my ex-home course, Sunol Valley Golf course, went out of business last month.  I played 2 - 3 times a week for 2 years not too long ago.  The course was done in by shrinking golfers, and 500% increase in water cost in the last 4 years of CA drought.  They could not make money.   Another ex-home course is now doing business as a golf and foot golf (soccer golf) course.  Golfing customers were not enough. Another course nearby (Santa Clara Tennis and Golf Club) is going to turn into a parking lot for a recently built football stadium. It is sad that despite improved economy in Bay Area, CA, golf business is in decline.  They have been in decline since 1990s but most of the courses around here survived 2008-9 recession.  The current drought and the resulting water cost going through the roof appears to be the final nail in the coffin for the weaker courses.   Sad.
    • Injury Question
      I didn't play golf for about 11 weeks due to it being difficult to play with work after day light savings time fell back.  Now, from the sounds of it, I played through the majority of the repair time as I walked 9 holes 4-5 times a week with 1 day of walking 18 for 7-9 weeks after the injury....I know, I'm an idiot. As it stands now I don't really notice it 90% of the time, its just something that pops up on a swing every now and then.  From the sounds of your healing time, I may have caused it to heal improperly leaving me with a hitch....  If I really just need to not do anything and it'll heal over time then I'd gladly do it, kicking and screaming the entire way as I already had a plan in place to push my handicap into the single digits by years end. I don't like the sound of having something happen as "I get older," I'm only 26 damn it .
