Sorry for bringing back this thread that's been inactive for 2 weeks, but now 6 months since I switched from my Predator Vantage shaft to a Revo shaft, my trial is over and I'm going back to my Vantage shaft. I'm just not happy with the feel and feedback I get from the Revo as opposed to the Vantage shaft. As I've been happy with my game lately, I'm just switching back to see what happens.
Another factor that may have affected my performance with it, is that the only way I could use the Revo was with a Predator butt with a 4-inch extension. I needed the extra length due to be 6'5", and the Pechauer butt and Vantage shaft I switched from was 2" extra length (1" butt and 1" shaft).
I will report back in a few weeks with an update as to my thoughts after switching back, once I've had same time to make a fair comparison.
