Welcome to the forums first off! I followed a blood trail a couple of weeks ago from a Magnus Stinger that a blind man could follow, NO KIDDING! That is what my buddy hunts with, I hunt with Muzzy 75 gr. heads and have had both great and not so great blood trails, but recovered the deer. Personally I don't care if a deer is shot with a two or siw bladed head, its a matter of where you hit them on how well they are going to bleed. Its just the same as a 1" cutting diameter verses a 2" cutting diameter, you hit'em right they are going down, some with a good blood trail some without. I've been using Muzzy's for over 14 years now and if the deer doesn't bleed its usually my fault not the broadheads. JMO
