We probably have met at some point then. Yeah aluminum arrows seem to give a smoother flight off the rest. The old knocks on carbon were larger than the shafts if I remember right which impacted the rest and screwed up flight.
We probably did meet! The aluminum, I guess I just got use to the flexing instead of the super stiffness of the carbon arrows. Carbon made for super fast flight, but not the best control for me! I guess the ol' story is this "you cannot teach an ol' dog new tricks".
