Thanks for all the responses.  I'm planning to wait until July and see if there's anything special that comes out on the 2010 Fatboy.  Once I know what's in store with the 2010's I plan to rent a Fatboy and a RK Classic, then decide from there.  I've always been a big fan of the Fatboy but the RK is tugging at me too.  I think, hope anyway, that spending a day on both of them will help.  I usually do an equal amount of time buzzing around town as out on day trips, so it's a hard choice between the two.  I guess my biggest concern is getting 3 or 4 hundred miles down the road and then finding out I bought the wrong bike.  Anyway, thanks for posting.
