I finished reading LSW this morning...what a great and comprehensive book! I'll be reading it again, starting with the "Decision Mapping" and "Game Planning" sections. Frankly, before I spend much time on Shot Mapping, however, my swing has to get more consistent than it is now, or it will be a challenge to find much meaningful information, LOL.
Regarding the latter point, using SVs has definitely lead me to focus on what skills are most important to practice. Specifically, I am focusing on Full Swing Motion shots (after spending the early part of 2021 focused on Short Game Motions shots and "Bead" putting drills) with Driver (get the ball in play as far as I can), Hybrids and irons (improve accuracy of approach shots) and Speed control for putts >= 25'. I will also be taking an AimPoint lesson in the near future.
I think leaving the clubs in the car where it’s hot contributes to the classic sliding down of the ferrule. I’m sure the glue/epoxy gets soft after long exposure to heat. Then we take our clubs out and start whacking away and …there you go.
