Lets see, My bow is a fred bear advantage hunter set at 70lbs. The draw length is 29", I am shooting 28.5 in arrows right now, but could go shorter. That is just what they cut them at for some reason. I am trying to figure out the best or fastest arrow I can shoot saftely. I read not to shoot an arrow too light or it could damage my bow. I am currently using Red Head carbon fury 4560's with 85 grain FT, but am changing to 100grain. I was trying to keep the weight down, but cant find any broadheads I like in 85 grain.
