I usually leave my top box on my Uly when in the commuter mode. It is just too damn handy for carrying lunch to work, tossing the helmet and gloves into and all that.
I do however agree that it is not the best looking arangement. Then again, when ya get right down to it, ADV bikes are not usually all that pretty to begin with, so it not not a case of making the bike ugly. It is more just changing the degree of ugliness. If I wanted a pretty bike, I would have bought another cruiser.
