i don't really know about that. i think muzzy or some company actually makes a gator gettor head. i'm not sure but i'm pretty sure. it just all depends. if all else fails the muzzys should work. as long as you're shooting where you're supposed to you should be fine.

i've heard some interesting stories about not quite dead gators also. be ready for a second or third shot. makes sure you have plenty of good quality arrows.
