RE: Slick Trick ????'s
I'm quite happy with the Tricks I use, and I've used them both--standard and magnum.
What I have however noticed, since some improvements were made with the 'sharpness' of the blades,it seems easier to burr, especially when ending up in the ground after a shot.
The older blades 'in my opinion' were a bit harder--less sharp. Unfortunately the trade off here is a sharper blade creates a better blood trail compared to a blade that not as sharp, but can be reused time after time.
