I THIRD the emotion that one should just let them SAG if for no other reason than to be identified as a NON POSER! I went with that theory on my Heritage and the bags developed a nice old school-droopy shoulder sag. All was well until a couple of rains developed a cupped lid on the right side bag and half the seams took a vacation when I poked a gallon of milk inside one day! Now I have a REALLY OLD SCHOOL Gabby Hays look that has me thinking I should just remove them all together before the fashion police catch up to me! :O
Well, that is one opinion, but I am already starting to have my shoulder droop, back slouch and seams pop. I figure I would take better care of my bike than I have of me.
