Launch monitors vs short game

Hi Tyler!

I don’t know if it’s made your radar, but there’s kind of a low-key war between two short game schools on the internet. One advocates a steep angle of attack and the other advocates a shallow approach, and both boast active successful tour players who use their respective systems. The steep guy consistently points to Trackman data that shows an AoA of 10-15 degrees, and the shallow guy points to an attack of 2-4 degrees but uses GC Quad, and both seem to have spin rates north of 7500 rpm for 10 yard pitches.
I don’t have a launch monitor, but I did a little video comparison using right triangles in a series of stills to approximate AoA at different distances from the ball and found that on a successful short pitch for me, about 18 inches from the ball my clubhead is dropping about 12 degrees but closer to the ball my attack is much more shallow; less than five degrees. It made me wonder, what part of the actual arc do Trackman and GC Quad measure? Is it possible that they measure the arc at different points and both these guys are actually advocating roughly the same motion? Watching their players in tournaments, ther doesn’t seem to be any kind of drastic differences in performance from either system.
Then it struck me that this is precisely the kind of tidbit that you might know.

I’d appreciate any light you can shed on the subject!

Thank you,
Zach

Yes, I'm aware of the AOA discussion. I was at the open forum last year where it was discussed by Joe Mayo, James Ridyard, The Chef, Brad Faxon, and others. It's a fun side show from the normal full-swing discussions.

I had Stan Utley out at my club in May and I had him hit a few shots. He hit some stock low-spinning chip shots that launched between 7 and 9 on Trackman. But he left a scuff mark on the grass before the ball. He describes his shot as shallow.

I have yet to see a discussion concerning what the different camps think are the key different moves taught by each school. So yes, I think if we looked at the method they each teach, they would be nearly identical. I like that low point height is becoming part of the discussion. I think that's a key missing piece for many who struggle with their finesse wedge play.

Happy Golfing,
Tyler

I certainly didn’t mean to insult your intelligence, and I would imagine you’re up on any new relevant knowledge, but you seem the antithesis of a trend hopper and this to me seems like a trend.
The physics of wedges mystify me. I can’t for the life of me understand how an open face 60 degree wedge can launch at 28 degrees. Even the contact itself- should distance wedges glide along the ground as well, or should they be steeper? When I use, say, my 8 iron to make a 50 yard shot, it helps me to glide along the ground, and that’s true up until my 50 degree wedge. I went up to watch the Sanderson farms and heard more than a couple pros slide into impact with mid irons and hybrids and it surprised me- almost a dropkick sound. With my 54 and 58 though, that same technique produces a much higher, less predictable shot and I have more luck trying to nip it. What are your thoughts on contact with short irons vs distance wedges vs finesse wedges? How does a 60 launch at half its loft even when the face is open? Does this wedge sound right?
And other questions of the universe.

Thank you sir

Don't worry, I wasn't insulted in the slightest. I like the idea that the best questions win. Or, as my mentor used to say, you can ask a question and feel stupid for a minute, or you can not ask the question and stay stupid your whole life.

The main answer to your question is friction. You need a few things to get the low launch high spin shot. You need, high spin loft (for spin) but a steeper angle of attack if you want the low launch. On top of that, you need friction and speed. I can't tell for sure, but those yellow golf balls you're hitting don't look like the premium variety. When I did my video for the distance wedge course, I showed how an old pinnacle range ball would launch almost 10 degrees higher than the proV1 (https://www.golfsmartacademy.com/courses/stock-distance-wedge-program/low-spinning-wedge-shot)

To me, that wedge shot sounds little dead, but it's hard to tell with those golf balls.

Typically golfers with your pattern have a harder time with the low launch high spin. Your tendency is more axis tilt and arms behind your body, those typically create a shallower AOA and contact higher up the face. A good recipe for high launch low spin drivers, but not great for low wedges.

Good luck! Happy Golfing,

Tyler
