i shoot rocket sidewinders, i have had awesome results. they are mechanicals that shoot like lasers and knock the hell out of deer. every deer that i have hit with them has had an awesome blood trail, even on marginal hits. buck i shot this year, 28 yards, slightly quartering away, head entered a little high but was shooting from a treestand and went through the other shoulder blade and was sticking out about 2 inches on the other side with a 70lb mathews. i wouldn't trade these heads for anything else, even though u shoot them once and they are pretty much done but hey thats all you should need
