Skipped through most of this post. I tried various Rockets years ago. The heads completely fell apart on 3 deer (ferrules bents, tips laid over sideways or ripped out, blades missing, etc.), and only got 3" of penetration on a textbook broadside hit, using a 65# bow. (All fortunately recovered.) I tossed the rest of those heads. Haven't had any damage to heads or penetration problems since switching to welded, one-piece cut-on-contacts.
