After shooting Muzzy's for 15 years and loving them...I can tell you the MX-4 is the last one of their lineup I would try. The MX-3 is good, but that 4 is just plain no good. If you are seton Muzzy, choose the MX-3 or the regular 4 blade 100 and you will be fine.

I have since moved on and now shoot the Steelforce Phathead. It is simply an awesome broadhead that will fly out of any tuned bow, plain and simple.
