Narrative:

I was coming in runway 27, got a couple of small gusts on final, so flew approach at 90 mph instead of 85 mph. Mains touched down in a wings level attitude. I don't think the nose gear had touched yet left wing started to come up, applied aileron to level wing. Wing continued to rise, airplane yawed to left. Applied right rudder to full extent. Right wingtip started grinding on runway, left wing continued to rise. Rather than go over on back, I released rudder and let airplane swing into wind and off runway. Propeller struck when wing came back down, rolled off runway to an easy stop. Called tower and reported I was off runway. I don't believe that there was any way for the tower to know that there would be a gust like that. Wind was reported as 230 degrees at 7 KTS.
