dirtythirtym30,
I'd highly recommend the Kenetrek 13" Grizzly for your elk hunt. I honestly prefer their K-Talon sole over the airbob styles. You're not as likely to break off the bobs in scree and rough rocks and I think the traction is just as good. I gave up on the bob style boots when Kenetrek started making their boots.
