I go along with what others have said, keep the RT and get the TBird. I have a Kawasaki C14 along with the TBird and each scratches a different itch. When I was looking, I came to the conclusion that it just didn't make sense to have 2 cruisers because I would probably wind up riding the TBird most of the time. So, I went the route of having 2 very different bikes so I'd have one to fit whichever mood I'm in.
Better living through chemistry.
