I think I'm going with those who like the natural, if saggy, look. I haven't asked my wife to go the silicon route so won't put stiffeners in my saddlebags.
1st thing I did when I got the FB back with new Springer bags was to park it in the sun and worked in about 1/2 a tub of Harley Leather Conditioner. Mean while the Bag Shapers were sitting in the sun getting pliable.
I just figured I wanted them nice as I paid good money for the bags.
I still wipe Leather Dressing on them once or twice a month.
