Interesting time with these new bikes. I am personally not impressed with the new GT specs, but I guess if you look at it as a high performance LT then it might do the trick.
If you need all the extra stuff for a passenger who needs the comfort, then maybe its not a bad choice. Personally, I find my 02 RS as big as I would like to go, but that's just me. The RS still handles pretty well, and has excellent weather protection, with some good get up and go. The new GT is so ugly, that will not be my next BMW ride.
If you want to look at something that might be a little different, but looks like a decent tourer, have a look at the new Ulysees from Buell, or the Norge from MG. They have some character and look like they would do the trick. The ST3 is pretty nicely decked out from Ducati, and handles like a dream.
