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.
What's up with the MX4's???
