Here's the problem. I want to buy easton redline arrows cut to 24.5" use 80gr. NIBB points and 2'' fletching. When I look up the arrow the hunting chart says 600's 6.9gr per" and when I look it up on the target chart it says 690's 6.3gr. per" which shaft do I choose. I shoot my APA at 54lbs. 26" draw. just seems that the 690's are to light I mean the complete arrow would only be like 260gr. And the arrow's are for 3-d only!
