First, 50#'s is plenty for deer sized game. Don't sweat the heavy arrows. I use 3555 Gold Tips out of my recurve. I have 2 sets of limbs (45# and 55#). These arrows shoot well out of both setups. For aluminum, I shoot 1916's for the 45# setup and 2016's for the 55# set up. 2018's will work with extra heavy points. In my opinion, good arrow flight with 2 blade heads beats heavy anytime. Dick
