To me it looks like SVB tries to keep his wrist cocked throughout the stroke, but with a loose grip he gets just a little break on the transition forward. Occasionally, (especially on the case ball or when he's just letting his stroke out) you'll see much more of a snap and maybe even a rolling wrist (the wrist roll happens in Earl's stroke shots a lot). I've tried CJ's hammer grip and snap forward (down into the bridge)...it definitely works, but like I said earlier I'm much happier with my current grip. I just can't get the feel down as well with this type of "plugged in" style. I like the cocked wrist part, though; it is VERY straight. I also think SVB uses such a long bridge for feel/action on the cue ball, like the Filipinos. He gets away with it, because he shoots so much centerline cue ball...plenty of draw and follow, but never more spin than he needs. To me, that's the key to SVB's genius. Putting aside the larger pocket zone part of CJ's "touch of inside" technique (not to debate the over-debated and controversial point), the dead-accurate vertical line you keep on all your strokes is probably the most useful part of the technique. Years ago I ran into a road player that told me (and showed me) that the best way to run a table was to use nothing but center line cue ball...he said once you learned how to run a rack with no English (just draw or follow), you pretty much learned all there was to the game. I'm thinking I disregarded the best advice I'd ever gotten (like a lot of advice in my life).
I've been paying A LOT more attention to top players since I took on the "touch of inside" technique (which I LOVE, btw)...Looking back on my playing history, the first thing I learned, fell in love with and over-used as a banger was draw...was convinced I only needed it and could slide/muscle the cue ball wherever I wanted. Then I learned how to spin a cue ball and deflect/throw balls with incredible variance...then that's pretty much where I stopped, no matter how "advanced" I became over the years. Now I see so many top players that tend to stun/center ball their way not just through games/runs, but through whole matches/tournaments. Watch how dead SVB's cue ball is most of the time...I'm talking spin, not draw/follow, which he uses lots of...most of his shots just hit one rail and back out to the center. Nothing fancy, unless he needs it and then he can spin whitey with the best; but mostly not. I think the vast majority of players (all levels, even up to A) tend to do WAY too much to the cue ball as a general rule, and it's what ends up biting them in the a$$ and ending the run.
