RE: 4 blade muzzy's flight
You'll be lucky if they hit the same as field point right off the bat. I had to do some palying aroud with my nock to get mine within 2 inches of my field points. They hit a little low. I shoot a fast bow at high poundage and that makes things a little more critical. I used to own a bunch of Spitfires and gave most away. I keep talking to people who have had malfuntions with them and don't have much faith in them anymore. If I was to use a mech I would go with either a Snyper or Rocket Steelhead.
