Right, in the video he cocks his wrist radially (always has, evident in that 12 year old picture he posts up sometimes) and it stays that way all the way through. Very early on in this thread a couple people asked for a video demonstration but he said "you can't see what I do because the motion is so quick and subtle" (same excuse used with other advanced techniques concerning video).
In other recent threads he talks about pausing at the end of his back stroke, "the gathering of the shot". That's a nice, feel-good description for people who do it (e.g. Buddy Hall), but he has no noticeable pause........never has, which again is clearly evident on video. In those same threads he advocates a shorter follow through. He has a short follow through only due to the fact that his grip hand is very forward on the cue compared to most modern day pros. Encouraging others with a more traditional, modern day grip placement to shorten their follow through is a mistake IMO.
CJ has a very unorthodox way of holding and stroking the cue. It works for HIM........not so sure it's good for others, esp beginners/intermediates.
As far as the hammer stroke goes, I'm not so sure most even really know what it really is. And I agree with DeadStick (see post #13) in that it's not "conducive to a straight, accelerating stroke". You say it's good for some shots, which ones? Certainly not for ones that need extra power. Video CAN show this, perhaps you could make one?
