I came from, and still ride, a GSXR also. And have logged about 3 or 4 thousand miles on GS's, just in the last 9 months.
I don't think anybody will ever convince me that having to do stuff with my left hand to initiate or cancel a turn signal, while I'm also using that hand to operate the brakes, the throttle, and maybe even steer a little, is a better (or even remotely as good as) design than the standard Japanese switchgear. Never mind that the positioning of the turn signal cancel button virtually requires me to actually shift my left hand position a bit to press it.
