I like saddles that I can get pretty proctological on. My riding style is, when I'm on the rivet or in a solo position, I'm way forward, on the tip of the saddle, and I need something that is reasonable, like that. So my preferred saddles tend to be things that also work for time trialists - Arione works good, I really like the classic Flite, and for some reason, the Concor Light, too. Things with skirts and rounded noses.
That's my personal preference.
Yours is likely to be different.
Find a shop that has a decent saddle demo stock.
