Yeah, I got conflicting messages from the collected wisdom of the internets as to whether or not reaming the shim was necessary. It didn't seem necessary before I glued the shim in place, but it was after I'd glued it in place, so I may have fitted it slightly off-centre. Lots of filing and sanding has made it work. The seat post is definitely straight, as I checked it.
