I've shot both. The Muzzy flew great out of my bows and were easy to tune. With that being said, they did have a minor problem that I didn't like. The blades would get small chips out of them went shot. It didn't matter what I shot them into, a b-head target or an animal, the same result. With that said, the overall b-head is TOUGH. I smacked a doewith one and got a complete pass through, after the arrow exited the chest cavity it hit the lower portion of the deers leg and went through that and burried into the ground. The head was in good condition with the exception of the blades having a few chips out of the cutting edge.

The G5 Montecs flew very well out of my bow and seemed to be one of the best long range fixed blade b-heads as far as accuracy goes. These heads are tough as nails. Also, it seemed like tuning the broadheads to the arrow was much easier and for the most part un-needed. The doe I shot had a complete pass through and the arrow burried itself into the ground. When I got the arrow out of the ground I found that the b-head was in perfect condition. It just needed a little sharpening but thats where the down side to the G5's is. The blades are pretty tough to get razor sharp.

Either one is a very good b-head, but as far as fixed blade b-heads go, I would go with the N.A.P. Crossfire. My buddy shoots them and they are top notch. They are super accurate b-heads that fly great at all distances. They, like the N.A.P. Thunderheads, have the sharpest blades out there. They are tough as nails and the whole blade cartridge can be replaced. If I was going to switch from my Rocky Mt Snypers to a fixed blade, it would definetly be the Crossfires.
