I will 2nd the slick tricks. 125 magnums. I have killed 7 bulls with the slick tricks and have been very impressed with them. Shot nearly completly lengthwise through a bull at 70 yds. Went in at the flank on the left side, and 6 inches of arrow and head were sticking out of the neck on the right side. I fubbed a shot at 20 and hit the bull too low. He was gonna die, but I figured if I could get one more in him even better.
I would stay away from any kind of expandables. I outfit 12 to 15 archery elk clients every year. Not wanting to get in the debate of expandable vs fixed. But I have seen way more bulls wounded with expandables. I will not allow them on our elk hunts and tell the clients before they come to not show up shooting expandables.
