I will look into those.

EDIT 1: I'm assuming those are what you have? Or why are you recommending them?

EDIT 2: I looked at those. The seat looks good. Light weight and all. I sure hope it feels better than the plastic Primo seat I have now. But the seat post might not be long enough for me. It's going to be for my flatland bike. Would the regular Macneil seat post work with the Kink Slim pivotal?
