I have been using a 12" mill bastard with OK results, just wheres your hands out.
I bought a wet grinder and the Grizzly 190 ate the wheel way to quick.
I love the Grizzly 160 & 190, I've had great results with them.
This pic shows how good they work: 55lb Habu, Grizzly 160, aluminum insert, 530gr. total arrow.

I now have bumped it up according to the Doc's recipe 58lb Habu, Grizzly 190, 125gr steel insert with footed aluminum over carbon, 4x3" feathers 650 grain total arrow with a high EFOC, Jumps right through stuff.
