The only problem with muzzys are the blades are a little weak. All shots with muzzys in the last two years were complete passthroughs.I don't know it the blades bent from the passthrough or from pounding the dirt on the other side. I shoot the 100 grain 3 blades, and dont have any problems with them hitting with my fieldpoints. This is with a perfectly tuned bow. Shooting a total arrow weight of just over 400 grains, fletched with Bohning Blazers. I do want to try the new Muzzy MX-4 this year.
