I just picked up a reign 7, don't have it yet but it should be here tomorrow. I just want to make sure the arrows I have will be fine. The bow has 70# limbs, maxes out around 72# is what the previous owner said. I'll have it set at 28" draw length but not sure about performance or comfort yet I'll have to mess with both and see which I like better. I have 2 sets of arrows though, one set is Easton Axis N-Fused 5mm in .300 spine 28.75" long 100 grain point with 50 grain brass insert and 3 fletch Blazers. The other set is Carbon Express Mayhem 350s 28.25" long standard carbon express insert 3 fletch Blazers. I just want to know which would be the preferred one as far as spine and tuning. I like the axis arrows but if I can do just as well with a little bit lighter arrow and pick up some speed I will.
