i use nap crossfires 100 grain 3 blade i just have never had problem with them y like them very accurate so haven't got resight my bow from field points to these
i missed 4 with my optima too i don't understand it either was at 50 yrds puttin 2 through same hole even usin shootin sticks still nothing i am using 250 grain tc shockwaves
i shoot carbon express maximas 250s but i don't pull that much weight i only pull 60 so like they said punch in bow poundage draw lentgh should show the lightest to heaviest arrow in that catagory
