I recently acquired a dozen 5575s from a local shop. Before I bought them I paper tuned the same shaft, at the pro shop, with every head they had, 100gr up to 200, and they all shot bullet holes. I thought this was odd, as I have had fits trying to tune aluminum shafts in the past with any tip. I also shot several on the indoor range. After deciding to give it a try I bought a dozen 5575 arrows. Shortly after, I took them home and shot them outside in the yard. Now it may be me, as the fletching is very bright and I can really see the spin on the arrow, but I thought I noticed arrow flight issues. I have the arrows cut at 29 inches with 175gr tips and I am shooting them out of a 58 pd BW recurve. What do you guys think? Not stiff enough? To heavy up front? I am relatively new to this, but I have begun to obsess over my arrows and how they fly. Thanks for the help.
