Hey guys I get mixed results from all the charts/software and trust some of you guys more. Currently shooting a Halon 32 6 50-60# maxed at 62# 27.5" draw 75% mods. Axis 400 at 27.25 with 16grn insert 100 grn head 3 fletch max stealth standard x nock. Planning to up my front weight to around 175grn and can't decide on 340, 300 or stick with the .400 spines that I already have. Also plan to buy a 70# backup bow soon and would like to shoot the same arrow setup through both if possible. Thanks in advance.
