I would definately say the slick tricks out of those two choices. Muzzy are good but i would prefer the steel construction of the trick vs. the aluminum construction of the muzzy.
I used the tricks last year and I was VERY impressed. I was shooting the 85 gr. then and I blew clear thru a huge doe, buster her offside leg and the arrow stuck in the ground. I had a blood trail stevie wonder could follow.
This year I plan on using the magnus buzzcut and the slick trick but this year I am carrying the 100 gr. magnum.
