Alternatives to Steamroller...

Thanks for the offer object, but I'm guessing you're in London? I'm all the way up in Manchester.
Just out of interest though, how tall are you roughly? I'm 5 11 and was going to go for the 56?

well if I get one (which is looking increasingly likely) you can at least try the 53 and see if it's too small. You on the Manc sub forum here? Harry Hall have got a couple of them made up in diff sizes to try out if you wanted.
