i'm been research on 2 compare arrow, well the eastson flatline got 8.2 gpi compare to gold tip xt hunter 5575 " black " at 8.2 gpi and camo at 8.6 gpi, and my arrow lenght was at 28 3/4 " long at 70#, hard to make decison which one i want to get..
will have to get arrow scale with uncut shaft and cut shaft see what difference weight on arrow..

for eastson i would go with 340, for gold tip 5575..
