I normally shoot 2514 aluminums with very good accuracy. I like the accuracy but I hate the fact that I bend and dent them while practicing. I love the durability of carbons and the flat trajectory, but they don' t seem to group as well for me. Every year I buy a new set of arrows and it seems like I end up buying carbons. The groups aren' t bad enough to steer me away from them and I feel the durability and flat trajectory make up for the small loss in accuracy. Does anyone else have this problem? Anyone know what causes this? I know plenty of guys who shoot them extremely well. I' ve tried every type of tuning possible. Yesterday I tuned it with a bareshaft until I got bullet holes. It' s been too windy since to shoot some groups to see where I' m at.
