I tried a Swift but found it was like a medieval torture device and i couldn't get on with it at all.
I think it was simply too narrow for my large rear.
I have a B17 Special on my bike currently on trial as a few people told me they were as comfortable as my other saddle.
A Flyer Special.
Its lighter than the Flyer but the jury is still out on the comfort stakes due it not yet being broken in.
I thought the Swift was the best looking Brooks saddle but I was very glad to see the back of my one.
Shame as I paid a small fortune for the Ti version at the time.
