Harry - If I recall correctly, I require a zero set back, i.e. completely straight seatpost for my R3 set up. I went with a Specialized S-Works carbon seatpost and got their pave clamps so that the carbon railed Specialized Romin saddle could be used. Love them both, but the latter was best choice for me based on saddle fitting/ sit bone analysis. The Specialized is great because it's completely black with a faint 'S' logo on it, which is covered up by my saddle bag, so it's a very clean look.
Jens Voigt doesn't complain about what suffering does to him, but suffering constantly complains about getting picked on by Jens Voigt.
