Do you know of any tour players that work on LAG? Of course there are 3 kinds... Accumulator, Clubhead, and Pivot Lag.
Clubhead Lag is "the secret". The tour players that I have talked to seem to have always have had lag, and are not really aware of it much... they just have it.
I know a fellow that went to the practice round of a major, and just filmed the hands of players coming into impact. He said every tour player had a forward leaning shaft, every one that he filmed. The only occasional guys that were not quite as good were... some of the club pros... this was the P.G.A. Championship.
