Give the upper, upper Rogue a shot. Up above Lost Creek lake. The hatchery scatter-plants some nice rainbows from Memorial Day to Labor Day all along the section from Prospect to Hammaker campground, but even if they didn't there are plenty of native 'bows in there for the type of fishing you're talking about. 4-lb test, 1/16 to 1/8 oz. Rooster Tails, Panther Martins. Whatever your go-to lure is. There are also some browns and brookies in there. It's clear water, so you have to be a bit stealthy to sneak up on the bigger ones, but you don't have to hike way in. You can pull right off the highway and fish, but if you're willing to walk a little bit, you'll have better results. Also, one other important thing to bring: DEET. Especially during the dry spring that we're having this year. Mosquitoes are already out in force.
