Some dont like em, that is very clear. But if you have your heart set on a mech, my advice is to go with the rage 3 blade. I have only this years experience with them, but on 5 does I got all complete pass throughs, all major damadge, huge blood trails and didnt have one run over 50-60 yards. These heads have been great, I dont plan on changing. We will see how they work on the turk come april.
