I'm planning on doing the same. I'm going to find 17s that are hopefully around 18 pounds. Lighter if I can find them. I had a cheap set of Rota Slipstream knockoffs running a 50 profile tire. I never had an issue with bending and I lived in a pothole filled city. The 16" SE Sport wheels are kind of heavy. Somewhere around 22 or 24 pounds each.
