anyone use a Brooks Swallow? I currently use a B-17 on my road bike which I love, but the seat on my Single Speed totally sucks, so I'm moving the B-17 over to my SS and my road bike is getting a new swallow. now I know the swallow is based on the b-17 but that's about all I know about them. What should I expect?

my bars are a few inches below the seat on my road bike, this was the main reason I went with the swallow, it was either that, the team Pro or the swift, but from the descriptions they didn't seam like the greatest fit for me.
