i have tried many mechanicals, and have 100% satisfaction with NAP's Scorpion XP 100grain. I also slip on two rubber rings just for that reason that you stated, and sometimes i field check my blades to maked sure the open easy and i will cut the ring, well now i have a backup. I have filled many tags in Ohio with that broadhead. Last year i shot 250# buck from a treestand, with the arrow entering in front of the white throat patch and exiting through the center/sternum of the chest.........the arrow was on the ground in 40 yards. I use the same tip on my compound........it is a tough little broadhead, but true placement is everything, along with never reusing the same blades twice. You want a fast clean slice through the arteries/veins to prevent/slow downclotting.
