60* Wedge - Distance Control - Impact Parameters/Club Design

Ya get the dyn loft with an 9 iron in the high 50s and hey presto ya got a lob wedge! A lat of people could've saved themselves 180 bucks!

well even better, they bent the PW down to 46, left the sand wedge alone and sold a shitload of "gap" wedges! PT Barnum had golf consumers in mind with his sucker comments I'm sure!
 
The ball goes through two phases at impact. First there is a slip phase and then there is a roll phase. The sooner the roll phase begins in relation to the slip phase, the more spin you create.

The optimum slip/roll sequence for spin happens at "around" 58 degrees dynamic loft....all other things being equal. If you don't have much forward shaft lean, then you are flirting with that threshold where the spin drops off and the launch increases disproportionately. Obviously, if you're at the "top of the curve" like that, you may experience a wider range of trajectory (low spinners mixed with high knuckle balls), and thus distance control.

Then you ask me: "well gee wiz, I'll just lean the handle more forward!" Not so fast sparky, if you lean the handle forward, this is usually in tandem with steeper AOA, so you are making a more "oblique" strike on an already "oblique" loft. Thus, your hit location is more likely to vary up and down the face....which affects launch, spin and speed.

Now, the other reason would be that, from a playing standpoint, golfers are more likely to hit partial shots with the 60 degree than any other loft in the bag, and of course, based on that you are likely to see a larger dispersion in distance control.

And finally, the cg/sweetspot on a typical forged 60 degree is very high on the face and heelward. The type of lie you have has a huge influence on your ability to get the impact up into that sweetspot......which has a huge effect on launch, spin and speed. Off a tight lie, you are going to be hitting it "thin" to some extent.

What about the knee high like shots from 30-60 yards out? How does that happen? It isn't a skull shot off the bottom of the club, but acts like one.
 
If you follow the trajectory line backwards thru the center of the ball, my logic would say that is the spot the where the club hit the ball. If it only rises to knee height then is there any other option other than a thin clip on the edge?
 
If that's where the sweetspot is, no wonder it is so hard to fade a wedge but easy to make them hook. Thanks virtuoso.

That will save me some time trying to learn to hit shots that aren't really feasible.

Magicmarker, the reason a lob wedge is hard to fade any significant amount is because it has a lot of loft to begin with, and you are adding more loft when you leave the face open to hit a fade. Because of that, it is difficult to have enough of a face/path differential to tilt the spin axis very much. On the other hand, they are easy to hook because you are reducing loft when you close the face.

A 3 iron is the opposite: easy to slice, very difficult to hook and keep in the air. If you close the face, you reduce loft from an already low lofted club, and the reduced spin (and thus reduced lift) makes the ball fall out of the air like a "dying quail."

Good rule of thumb: low lofts are easy to fade, high lofts are easy to draw.

PS: this can be seen in practice when Bubba Watson hits a duck hook with a wedge at the Masters, and when Tiger, who is very dynamically de-lofted at impact, mostly hits trap fades, especially with lower lofted clubs, and often into left pins.

When I try to hit my driver a fair amount higher I hit it straighter. Is that becuase I'm stretching out the top vector of the D plane through more dynamic loft (assuming other variables are somewhat constant) and by stretching out the top it becomes harder for the face/path disparity to tilt the axis of the ball?

What's the typical max height on tour for a driver (assume 118+ clubhead speed)? 120 feet?

40 yards is on the high end; 30/35 more average
 
That's what I thought about their max height. I was fitted for 90+/- max height with my driver, however, when I hit it very high it goes straighter. I haven't been on Trackman to find the exact why but I assume there's more dynamic loft to stretch the top vector from the bottom vector so that face/path doesn't affect axist tilt as much.

cwdlaw, I really couldn't say for certain why you hit the higher driver shots straighter, because when you say "assuming other variables are somewhat constant"....well, that is an extraordinary assumption...even for a tour pro. You may very well time the face angle better when you deliver the club with more loft...or you may deliver it better, and the higher dynamic loft may help, or some combination there of. Or, all of the above, and you have a more consistent impact location, and so on.

The difference in dynamic loft (and assuming attack angle hasn't changed...if you are truely doing that) is not going to be that different between the higher driver shot and the low driver shot. Is a couple degrees of loft enough to bust through all the other noise and adequately account for demonstably straighter shots? I have no idea.

Am I correct that the more the top vector goes vertical (in relation to the bottom vector) the harder it is to tilt the axis?

My question was a shot in the dark and I need to get data. Maybe by "adding loft" through body movement/axis tilt/hands I get a better face/path relationship.

yes, you are correct, the more the normal of the face points "up", the harder it is to get it the normal to point to the side in relation to the path the head is traveling.

If you hit the ball straighter by adding loft that's fine, but how far do you want to take it? Higher lofts will always hit the ball straighter than lower lofts. If you are meeting a more optimum vertical impact, go for it, but I wouldn't sacrifice that just because you might think the face/path relationship is better.
 
Hey Virt,

Pretty sure I know the answer, but just want your take.

Around what loft does it become more beneficial to fade the ball?

Thanks,

Lindsey

Thanks. I need to stop guessing and get on Trackman. I'm fortunate enough to have enough length that I can add some loft and still have wedge in!!!! Who knows, I'll have a new swing thought in a couple weeks anyway. :D
 
My swing is pretty much the same for the past 10 years, but my thoughts still change. ;). Of course, with BMan scheduled for the 9th things could get very interesting.

You also have to factor in ball speed too Lindsey, i see where you're going with this question and i have a guess as well but someine with more ball speed can get away with tilting the d plane more to the left because their ball speed will keep it in the air longer versus someone who can't.

BUT

My guesstimate it somewhere around a 4-5 iron
