It may be a mental thing from me, but I will never hunt with anything but a fixed blade. I shot two deer with the traditional 3 blade Muzzys this year...one a good hit but no pass(severe angle upon impact), and the other a clean pass through. All in all, the last 6 out of 7 deer I have shot with Muzzys over the past 3 seasons have all been clean pass throughs. I am sticking with them.
