In my experience, making noise with mulies is about 50-50 at best. 50% of the time it will stop them, 50% of the time it will blow them out and you won't see them again. Other senses, I'd rate the mulies nose lower than a whitetail's, but his ears and eyes noticeably better. I'd also check out "Hunting High Country Muledeer" by Mike Eastman. Great book even if you aren't hunting the high country, this guy, like Dwight Schue, KNOWS mule deer. Other than those two books, I can't really recommend any others.
Good luck,
Mike
