Manti Early Rifle

My grandfather was fortunate enough to draw the early Manti rifle tag and I plan on helping him out.
I've never hunted the unit (but I've fished Huntington Creek & Res. before the Seeley Fire a couple years back) and would be more than appreciative for any tips or pointers to get us started.
I have a spot or two already in mind in the area that I'm familiar with & I'd love to bounce some ideas off anybody that has experience with the unit.
