I've used the old stly Bear blades with bleederes and really like them. I prefer a blade style over the "pencil point" style because i believe that it cuts through instead of poking through. This may make a deer not even know he's been shot.

They all clearly will work. Seems to me with bow hunting, what you cut is what you got. I like the looks of a blade with 4 slicing surfaces. If I loose one on impact, (Rare but possible, I still have 3 going through.

I got a nice 8 this year using it and had a clean pass through double lunger. Deer made it about 50 yards from point of impact. Easy to track too! He was still close enough to hear him pile up in the woods.
