I know, not a technical posting, but....just got my 3rd buck with my '08 Moab. 3 years, 3 P&Y bucks. This one barely makes it though. lol Used Rage 2blade heads, and they worked very well on a not so great shot. When deployed, the blades act like barbs keeping the arrow in the animal. An unexpected result, but a good one. Saved me on this one!
