I was in Daytona for Bike Week on Sunday and visited the booth of a vendor named Twisted Throttle . They sold a unique tank bag setup that required no straps and no magnets. It used a locking ring on the gas cap that was not obtrusive and held the bag tight. You could also get one with 12V power to charge or energize your toys in the bag. With so much going on, I never made it back to talk to them more about it. I just figured I would go to the web page when I got home. Well, the web page is less than informational. I'm not even 100% sure who the manufacturer is. Does anyone know anything about them? Used them? Opinions? I'm not that far from Daytona so if I get some positive opinions, I'll drive back over and see if I can't negotiate one of them good "Bike Week" deals.
