Ok I know a lot of you guys like to tinker around with all your equipment. (I mean bows and stuff... geez

)
I guess for me I like to have solid stuff that doesn't require me to always be tuning and adjusting. So in my pursuit to find a broadhead that flies great out of my set-up, I've tried alot of them. Always comingback to mechanicals fro accuracy. So as I said I don't like leaving things to chance (will it open etc..)
Anyway to get to the point I picked up a pack of Muzzy Mx-4's ..these friggin things may fly better than my fieldpoints! I never considered a 4 blade broad head. Why does it seem so many avoid them?? What am I missing?
What's 5-shots link I want to seee if he's tested these??
