I shoot Muzzy's and absolutely love them!!! IMO, you will be making a mistake not sticking with the fixed blade head. If you MUST go to a mech. I like the Goldtip Gladiator. Many moons ago I shot the Gladiator. It was devestating on deer. The reason I swtiched to a Muzzy was I liked the cut on impact tip. I have yet to lose a deer with Muzzy's. Try the Gladiator if you want a great mech. head. Better yet, stay with the Muzzy!!!!
