I have used muzzys for many years and they fly exactly like my fieldtips. They work perfectly for me and I would have no reason to try another head. As far as the tip, I have never had any issues with penetration. In fact I hit a buck too far forward a few years ago and it took out both shoulderblades and dropped him on the spot. There are a lot of great broadheads on the market. Most of them should shoot just like filedtips in a properly tuned bow. Good luck.
