Some suggestions:

Since saddle comfort is such a personal thing, you should try as many as you can. I also think that you should ride a saddle more than once before you discard it, unless of course it truly harms you on your first ride.

See if you can borrow a friend's for a week or so. Try swapping with others who have saddles they don't like. Your local bike shop might also have some used saddles that you can try. They might also have take-offs you can buy at a discount -- these are saddles that came with a built bike, but which the buyer asked to have swapped out for another saddle. Buy one used. If you love it, you can always get a brand new one. Terry has a 30-day return policy and I'm pretty sure they make non-cutout saddles. WTB makes a sampler kit of their saddles (they're black & bright yellow so they're easily identified) so that shops can lend them out.

Good luck,

Cari
