i only use rocket sidewinders. They are awesome heads. the pentrate great even at longer distances and open a huge hole, leaving a nice blood trail. every animal that i have killed with a bow has been with them including 5 deer and a fox and alot of missed turkeys[:@]. my first buck that i shot with them i spined him and he dropped like a sack of potatoes. I wish i would have gotten the butcher to cut out that verterbrate because it probably looked like the muzzy bad to the bone picture. My buck i shot this year, the arrow entered him and then cut down coming out the other shoulder blade by like 2 inches. would i recommend them, YES! they fly like ur field points(sometimes better for me at longer distances because it seems as though they stabilize the arrow more in flight). i plan on probably using them for moose or caribou sometime in the future.
