Wedge play...
Direction: There is absolutely no reason to hit a wedge any great degree off line. Okay, 5 - 10 yards left or right if your lie is awkward, but you should be mad at yourself.
Distance control: this is bit more challenging. Sure you can have four wedges and think of a clock and how far back you want to swing your arms, or, you can learn to feel the mass of the club in your hands, learn to leave that mass alone and deliver the undisturbed mass to the ball with your pivot. Yes, I'm talking about lag pressure.
1. Address hands
2. Become impact hands
3. Impact hands get stressed by your pivot and the inertia of the club.
4. The pivot guides this stressed condition
5. If you don't mess with your impact hands (leaking or flipping or helping or quiting or whatever), and enjoy the "STRESS" you'll be able to guide the lag pressure via your pivot to some wonderfully accurate and dependable shots.
I'm sure I'm frustrating some with simplicities, but it really isn't that hard.
BMan could do one hell of a short shot video. I'll be first in line to buy it.
