If you head to Slick Route, it might be worthwhile to check out Memorial (to the right of the Regular Route). There are a few bits of 5.8, it's ~8 pitches, all sport. The South Fork of the Clearwater (outside of Grangeville) also has some climbing on Lightning Dome, but I believe it is harder than what you are looking for. If you want to go "cragging" it might be worth your while to check out the Pins & Needles outside of Donnelly, Id. Have fun!
