Talk to WWJD First, He did this most recently, find out if he is real happy. I think it really comes down to what you want or expect the bike to do. If your into carving corners a 180 might be the way to go, if you just enjoy riding the twisties and otherwise rippen around, get the 200.
I kinda like the fatter rear tire back there but it's mostly a look thing... No real reason.
