I did the AES Casner ride back in '11, here's my recap of the route if you're interested:
http://schillingsworth.blogspot.com/2011/06/aes-casner-mtn.htmlBy AZ standards I don't think that route is all that rough, sure there were a few short chunky bits, but if you're cool with 1/2 mile HAB's, then there should be no concern. I don't think any of my HAB's were more than a hundred yards or so.
