Just like any other saddle. If it works for you then it does, if it doesn't it doesnt. The pro/con about the SMP is they have a huge selection of combinations that feature width, padding, shapes...etc. if you try 1 and it doesn't work, it's like picking straws which model to try next. I tried a couple models and felt like inwas riding on 2 rulers up on their edges. But, I hear once you find one that works, they are amazing, but isn't that the story with any saddle?
