The saddles you mention are great for all day up and down the Alps as long as you are wearing bibs with a chamois. I've got a racing saddle on my road bike and it's great for what it is, but I hate it in street clothes.

My b17 on the other hand, is excellent in jeans or slacks or anything else.

What I don't understand is how people can be comfortable on a b17 with a lot of saddle to bar drop.

Chacun a son gout.
