I haven't done as much testing as 5shot but I have done a few tests of my own before deciding on slick trick magnums.

I've shot stingers, montecs, muzzies, thunderheads, sonics, razor caps, rocket ultimate steel, and slick tricks into cinder blocks from the same bow, on the same arrows at the same distance. The only broadhead that was undamaged and shootable again was the slick trick. In fact, Ishot it 4 times into the concrete and it still spun true.

True you aren't shooting into concrete when hunting but you can't argue with how tough a a broadhead is when shooting it into concrete.

I have shot them side by side with other COC heads into targets and the slick trick would out penetrate nearly every time.

The slick trick is extremely sharp, flies exactly where I aim and, busts through bone like a bullet, and cuts huge 4 blade holes.
I have not found a broadhead to date that offers as much performance as the slick trick.
