I need some 250 spine arrows for my 80lb RX7 Ultra and trying to keep them under 10 GPI. I bought 2 dozen GT Airstrikes buy I'm not loving them. I also bought a dozen GT Pierce Platinum's that I've been waiting on some 2.5" Q2i fletches so have not tried those yet. Problem I have with those is the .0025" straightness. So, looking for lightweight 250 in a .001 spine.
