The topic/argument in regards to the weight of the 150s has come up on several occassions lately and although they are marked 10gpi, many have found them to be closer to 11gpi. My setup is a 30" 150 with standard inserts, 200gr points, wraps, 5" inch feathers, and signature nocks. Total arrow weight 570gr. This is close to 30gr heavier than they are supposed to be. Fine with me though, they fly great and pack quite a punch.
I shoot them from a ChekMate Hunter II that is approx 55lb at my draw(29").
