For what's it's worth, I picked up a 314 CAT around March of this year. The shaft had been 'juiced', sanded down. I have been playing with 'spin' for 46 years & this shaft definitely applied more spin with less effort. In fact, the spin to 'deflection'/squirt ratio was more than what I wanted to deal with from a subconscious re-training perspective for long shots, so I sold it. I then purchased slightly used OB Classic & McD i2 shafts. They are fine & I like both very much. However, neither one puts as much easily produced spin on the ball as that 'juiced' 314 CAT, at least not from my perception.
The scientist will disagree, but if a LD shaft is deflecting more than a standard shaft in the downward direction when apllying draw, I feel that that is the reason that there is a difinite perception, for me, that they put more spin per foward movement on the ball than a regular shaft. They hit with more of a 'swiping' strike. The difference may be small, but it is a difference that can be 'felt'.
Raymond Floyd can feel the difference of one(1) extra layer of tape under a golf grip. How thick is one(1) layer of tape even when multiplied by 3.14? John Havlachek (spelling?) can sense the goal being 1/2 inch too low in warm up.
I know what the physics says, but if the parameters are different, then the results should be different. Some will say, it is, they delfect more & cause less cue ball squirt.
Yes but does it stop there? By deflecting more they cause a different affect on the cue ball. I shot a cut shot with the object ball about one(1) ball off of the long rail & about 1/4 diamond out from the corner pocket with the cue ball near the diagonal pocket. When I shot the shot with that juiced 314 CAT, I did so with hard draw expecting the cue ball to carom into the long rail with draw spin. Instead, it drew sraight down the long rail and scratched into the corner pocket. I was shocked & could not believe my eyes so I asked my opponent who was standing looking straight down that line if the cue ball had made contact with the rail & he said, 'No... & I can't believe it'. I have never done that in 45 years of playing with regular deflection shafts.
Take this for what it's worth, but keep in mind that I have no motive or interest in your ultimate decision. I'm simply telling you the truth from my experience, perception, & perspective.
