Just received and installed mine yesterday. Anyone sitting on the fence about these should just get'em. You won't be disappointed. What a difference in riding comfort. I got the E.5L model which, I think, is only a 20 degree arc but with my Ultimate King seat it gives me a lot of legroom. With that arc and that I put the offset to the inside it keeps my boots a fair amount above the road even in the turns. I did 750 miles in two days this past week and my legs were just aching all during the ride. I just need to stretch out the legs. With the MOPs I think I could do those miles in one day in complete comfort.
