What I am getting out is and I sure don't mean any offense, 7 years is not long enough to understand why we all left aluminums in the 80's in the first place, and went to the carbons. How it evolved into people believing aluminums were so fragile they would bend by dropping them, and then coming back after forgetting about them for so many years, and seeing we really didn't come far at all. Andactually carbons in many ways are not as good as aluminums. If your mentor shot better with carbons than his alums, then obviously, his bow was not matched properly. If one's spine is matched properly, and your spine is consistent, and arrows straight, there is no reason in the world, he should have shot better with your carbons. I know you will come back with he's been doin this this long, and he's the greatest since slice bread. Carbons are not magic, and improve your score just because they are carbon. There has to be other factors at work. With carbons we do not have near the selection as alums.

I am very frustrated these days with carbons. I always find 10%-20% out of a dozen that have very inconsistent spines or not straight enought to put a broadhead on.

And also experience has showed me, that you can get much better, and quieter performance from a 500gr arrow. So here I am the last several years only buying heavy carbons at 11gr/in.

So just in the last few months, it dawned on me. I am back where I started in 1982.
