Having played extensively with both shafts I would give the nod to the Cuetec for the following reasons – in no particular order;
1. Better CF Finish. Compare a new Revo and a New Cynergy side by side and look at the quality and consistency in the finish.
2. Feel and Touch. While the REVO certainly is low deflection, it's also very muted in terms of feedback. If I can't feel how I hit the ball, how do I develop good muscle memory? I have worlds more touch and control with a Cynergy shaft.
3. Ferrule. You can replace the ferrule on a Cynergy shaft. You can also actually see it for those of us with eye dominance issues. A white vault plate on a Revo is useless when you're chin down on the ball. It's too short to be seen.
4. Straight Taper. While both of these shafts have very low rise tapers. I prefer the straight taper of the Cynergy, especially when I've been left on the rail or I'm bridging over a ball.
5. Price $$$$. The Cuetec is available in so many joints at $399 and it comes in a better package, and has a limited lifetime warranty, just like the Revo. I'll use that $100 bucks I saved on trying the latest tip du jour for the hell of it.
6. Pro Feedback. When you look at the number of Pros who have dropped using the REVO and gone back to wood compared to every Cuetec Pro using Cynergy it gives me pause. I know Predator has an army of pros, but their best guys aren't using it (Filler, Kaci, Appleton, Biado, Albin) This probably isn't a good reason, but it makes me think I'm right about the tough issues with the Revo.
Anyway, just my two cents, what do I know – I haven't seen a table in what feels like forever. Stay safe !
