Kevin; Nice job. Looks good. Your hard work makes it easier for the folks on this forum.
I'm curious about the order of your setup. You start with the feet together, then twist, and then widen your feet to your stance. Is that what Kiran recommends also?
My procedure has always been to first set my stance width (I do this first because it can be different with different irons and woods). Setting the stance width first also assures me I am in balance for the club I'm using and the shot I want to hit (draw, fade, straight). Once I have the stance width, I then bend from the waist forward to set the particular club I'm using. The the last thing I do is perform the twist. I then know immediatialy if my head or torso is too far to the right and I can adjust. I will try it your way and see how it goes and report back.
Don't misunderstand. I'm not saying your procedure is wrong. I just assumed from the beginning that the golfer would fist set the stance width according to the club being used and to make sure he's in balance.
About the distance of the butt end of the club from the zipper. I don't know what club you are using in the video, but it looks about right. I'd suggest though that the distance could change with a shorter or longer club. It could also change depending on the anatomy of the golfer (taller, shorter, longer arms, shorter arms, heavy torso, slim torso). I don't think there is necessarily a cookie cutter distance for everyone. I'd suggest it's what keeps you in balance and lets the arms swing freely from the sockets without interferance.
The twist you perform is better than in your earlier videos since you head doesn't get outside your trail knee too far, and your posture seems to be better (though only you can say if you hit the ball better from that position). As I said before, if you start the DS from a position too far to the right, it will be more difficult to get a good rotation aroung the proper axis. I hit a lot of heel shots and pushes before figuring out that I was twisting to far to the right at setup. I think there is room for the golfer to adjust a little to what fits their swing mechanics.
Again, thanks for the videos you post and your dedication to teaching the game.
