Indy Hunter has a point, I'LL reply as to what I would use if I had only 1 choice of head for the rest of my hunting days.
Rocket Steelhead (probably 125)
They have placed at the front or VERY close to it on every penetration test so far, and the solid steel construction (and shorter blades) would reduce if not competely eliminate AK's problems.
But, the TOP reason it technology. in 30 years, we'll see bows shooting 400fps or better. THAT kind of speed will be VERY tough to get fixed blades to fly 1/2 way decently.
Right now, I am shooting "slick trick" heads (cause they look to be a neat design...just trying new things)
In the past, I have used Muzzy 3 Blade 100s, and Shockwave 100s. and in EARLY testing, the Shockwaves out penetrated even the Muzzys (EARLY testing...still developing the tests themselves)
