got to have a broadhead this year for a elk hunt and have narrowed it down to 2. the sto or the grizzley. i need 160 gr. with and a broadhead adaptor to get 200 gr. how hard is it to get a good edge on the grizzley's? i have never sharped a head with the single bevel.

They are both great heads. Pick one and learn to sharpen it and don't worry any more.  serious

Like Chuck said, they are both excellent heads.  If sharpening concerns you then I would hands down recommend the STOS, much easier to sharpen.
