I've seen you swing and anything can be grooved. Cookie had a dip on his downswing as well and hits the ball quite well. Short game not so much...hehe
Seriously...I would never recommend it but it can be grooved. It changes the swing plan mid swing and the timing has to be perfect

Freddie, what does it change when compared to a "normal" swing? I honestly just don't know, because I've played with it all my life. It's quite odd because I don't dip on any short game shots. Chips, pitches, etc. I don't have the move but for some reason it's mostly in my iron play. I don't have much of a dip with the driver either. Kinda odd.
