I'm getting back into cycling after a long layoff and it seems that everything has changed. I'm now riding a nice Rolls, and that and the Regal were my faves, but I gotta believe that saddle tech has come up with a lot of new and different comfort features. Is there a good guide to choosing, say, a Fizik saddle. I'd rather not do the trial and error thing too much.

PS: I'm 200+ so I need tough rails.
