Damn mechanicals, have made me poor due to a high taxidermy bill! Seriously, mechanical haves made me a more successful hunter, I naturally torque the bow, I have a hell of a time tuning, but can get fixed blades tuned to the same point of impact as the field points, but in hunting situations with adrenolin flowing my form suffers, and fixed blades have lost me animals, since I started using mech's my arrows hit where I aim. I have not had a single failure with my brand of mech's, and have 30+ kills with them! But I do have to mention that I have not killed a elk or a moose with them, only deer and bear, but I did shot a bear last fall, with a 76 pound elite bow, a fmj arrow, the bear was quartering towards me and I hit the front shoulder, the only thing that stopped the arrow from passing through was the blazer veins and they were pealed back on the shaft, the fmj arrows was mushroomed but the broadhead was still intact! I don't recommend a quartering shot but the bear had half of its head blown off and I had to put it out of its missery.
