I ended up buying the Wunderlich seat and really disappointed that it's no better than the OEM seat, 40 mins riding and my coxis starts to hurt, do these seat have a break in period?if not then I'll have to send it back :-(.
I've got a Sargent seat and I am looking to do a swap for a Wunderlich Seat if interested ?
