I think the springs look great...but then I'm a retro freak....
I have them on my hybrid (B68) because I do some really crummy roads on it and they are quite good at absorbing shock. They are heavy though.
I have the B67 (same saddle w/out springs) on my road bike and the difference on bumps is noticeable. But since I rise out of the saddle when I need to, its no big deal.
I think what Knot said about saddle shape has been really useful. Do you prefer a T shape or a pear shape. I love the T shape of the B67/68 because the nose does not chafe my thighs...it's "invisible" unless I want to grip on a turn.
I can;t remember the advantage of the pear shape.
But Wall bike.com has good info and if you call them, they're helpful and nice. And if you get the wrong one, they'll replace it.
Discipline is remembering what you want.
