Ive been using the Fizik Aliante and am somewhat pleased with it.

However I am getting the Bontrager Inform saddle when my shop gets it in a few weeks. Long explanation short, it was designed by the University of Wisconsin doing a Biomedics study (not just a urologist, so ladies there are ones for you too) and the comfort and variation of sizes make it one of the best saddles out there. (according to my buyer who tried it at Trek World this year and has tried many more)
