Personally, I like a 2 blade, cut on contact that is sharp as all get out. I like em to be moderately wide, somewhere around 1 1/4" wide, and heavy.
I really like a head that has a triple thick tip, and the thicker the better. Less chance for tip deformation on contact with bone.
Some of the best, IMO, are the STOS 160, Ace 160 standard, Eclipse 145, and Ribtek 145.
This year, my quiver has Eclipse 145 gr. It has a smooth, teflon coated ferrule, takes a great edge, has a very thick tip for its weight, and is 1 5/16" wide. Fits all my criteria, although I would like to see it in 160 gr.
