If you're just doing weekend rides then lots of choices could work. I love my Trials rear tire on my WR250F, but I fear high speed pavement sections would toast it with the HP of your RFS KTM. In slow, Steep, rocky, technical riding, Trials tires rock ... and wear incredibly well too! (TWO SEASONS!)
If you were doing truly long rides, packed up with gear and including lots of high speed pavement in the run, I'd go with Crashmaster's "Mullet" combo idea: Knobby of choice up front with a hard wearing 50/50 on the rear. (Mefo, Heidenau).
Really depends of terrain, load, pace and length of your ride.
