I've a Pro Logo Nago PAS in the cellar - it's the single most uncomfortable saddle I've ever ridden. Uncomfortable at first, and then verging on complete agony as the miles roll past.
I'm not a fan, although other folk tell me that they love this saddle - indeed, I bought it on the strength of such a review (and a similarly glowing one on bike radar). I've been on the point of putting it on
ebay many times - if you like a firm, fairly flat saddle, you might get on with it, I suppose...
