I've killed deer with rages before with pretty good success. I just didn't care for them deploying at the smallest bump. Just talked to a buddy who just came back from elk hunting and had a heartbreaking experience with a rage. Shot an elk at 30 yards, got 2" of penetration and the arrow fell out. The broadhead snapped off at the insert upon hitting what must have been a rib. Never had a prayer of finding the elk. Not saying it can't happen with any other head, but it was a rage and thought I should share.
I just think there are other options with less to worry about. That being said, I'm shooting smoke ramcats this year, and boy they are mean looking. Can't wait to try them.
