I gold tip arrow with 110 grain brass insert and 100 grain head is normallythe equivalent (FOC)of an arrow with an aluminum insert and 150 to 170 grain head. I use Easton Power Bolt carbon shafts with aluminum inserts and 170 grain field points for 3D shoots and 170 grain NAP Spitfires for hunting. I have found this combination the most consistently accurate. Some arrow combinations can be shot very accurately but only with great effort in holding perfectly still, etc. This heavy arrow combination that I shoot seemingly just puts them in the centereverytime without much effort on my part. I like that My arrows for the Vortex weigh 481 grains.
