Congrats on drawing a rare Oregon MD rifle rut hunt. I've hunted the unit a bunch, in a small area, for cows. I do know there are locals on the south end of that unit who do watch some very nice deer, pretty sure there are a few good ones scattered about as well. Suspect all you need to do is find concentrations of does and watch them.
No idea about your MD hunting history or goals, but unless its your stomping grounds, you have local help, a guide, or another in, I'd pop anything to or past it's ears with decent height day one. If you can hunt more than 4-5 or so days, then I'd be a bit more picky, but absent an advantage, not too picky. There are some very good Whitetails in the unit too. I'd give the bio for the area a shout
