Double Wrist Action is NOT the COCKING OF BOTH WRISTS! IT IS HAVING A COCK AND BEND IN THE LEFT WRIST. SWINGERS SIMETIMES DO THIS VERY WELL. WHEN THE LEFT WRIST BEMOMES FLAT AT IMPACT... IT IS OK. I believe you'll see that Charles Howell also does this.

Now as far as Hogan... I have seen pictures where his left looked FLAT at the Top, and some pictures where it looked Slightly Bent. They were all FLAT at IMPACT.

Tiger Analysis... It would be interesting to see if the "cupped" players tend to do what Gary Player says in his analysis. I doubt if it has an effect on Delivery Path... but it may. Some guys I can think of "cupped"... Howell, Price, Hogan, Player. Like some have said... this somewhat depends on one's grip.
