When not using TOI which is still hptting offset, I hit offset for some form of diagonal english spin for nearly every shot other than a straight stop shot or straight folow shot & then I'm hitting off center low or high.
I had been spinning the ball for 45 years before picking up a Predator 314 CAT shaft that had been taken down to 12 mm.
I've played with 13 mm & 12.75 mm before that.
I look at & use the inside of the tip, nearest to the center of the cue ball as my focus point & not the center line of the shaft so I 'know' where I am hitting the CB &/or I am consistent in what I do.
I can put more spin on the ball more easily with that 314 shaft than any shaft I had ever used.
Since then I picked up a Mcdermott i2, an OB Classic, & 2 OB Pro shafts & a couple of the older Muecci shafts.
I can spin & draw the ball immensely with any shaft as long as it has a 'good' tip on it.
I can put spin & extreme spin on the ball more easily with that Predator 314 shaft than any shaft I have ever used including the ones I just mentioned.
That said, I don't really like it. It's great for less than 2/3 of a table shots but for full table shots with english the swerve far out weighs the squirt & the ball will cross the line & I don't like that & having to gauge for that as that is not 'natural'. Also it has a whippy feel to it.
Like bdorman said, I don't care what the 'science' says. I know how that shaft & other shafts relate to what I can & can't do with them.
That's the bottom line for me & IMO should be for any player of the game.
Best 2 You, Tom, & All,

PS A pro tennis player can get 3 balls out of the 'can' made at the same time & not 'like' & not want to serve with one of them. John Havlicek could tell during warm up if the rim was 1/2 inch too low or too high. Ray Floyd can tell if the golf grip installer put on one extra layer of tape.
PPS Does one layer of tape make that much of a difference. It does to Ray Floyd.
