kt,
If it works, don't fix it! Sounds like you're pretty well set when it comes to broadheads, so stick with what works for you. I've heard some really good things about the Rage broadheads, but for that price they can have 'em. I'm really liking my 6 for $32 (give or take) Rocket Ultimate Steel heads right about now... A friend gave me some Grim Reapers to play with, so I might try them, but for my money, the tried and true works. Stick with your muzzys - you won't regret it.
