I've looked at the Giant Loop myself and am thinking about getting them for my monster. I have "sport" saddlebags which would fit GREAT except for the stock turn signals being exactly where the saddle bags would sit. The Giant Loop are pricey, for sure, but it seems like another example of "buy now, keep forever" as opposed to "buy now, replace with ones I should have bought anyway."
