No you don't... at least not at Len's. LOL He'll tell you exactly what he thinks. LOL He's an instructor and went to school years ago with this PSE guru, the Russian instructor.(I think he was Russian) Anyway, he can point out more flaws than you want to know. LOL And it's different from shot to shot. You'll let an arrow go and he'll say, "You know what you did wrong that time"? LOL. It's humbling. LOL The other day he was standing there face to face watching me and I let one go, well I creeped and jerked and let down and who knows what else. He just turned and walked away saying something like, "What was that". LOL I'm not a bad shot. I can shoot X's more than half the time, andGodknows I go into the zone with a deer in front of me, I just have momentary little glitzes, but he sees them all.
