anyway I see you thinking about saddles.
saddles work like this: they have different shapes. and only one shape will suit you!
for me its selle italia slr series. these are basically flat saddles seen from the side. and wtb banana "v" shaped ones suit me very badly. many people swear by wtb "v" saddles. but for me its total crap. its the wrong shape. for you this could be good though. kinda doubt it though.
I guess is what I'm saying is that you use this bike to find out what you really want then sell it and build the next one from scratch. with what you really want.
