Thinking of adding a tank bag to my collection, has anyone had any issues with them not staying in place or rubbing/scratching the paint?

 

Wolfman makes pretty good dual sport tank bags that are pretty small and might fit a sporty. I prefer a tank bag as what you need is right there. Keep us posted I'm curious how it will work for you.

 

I have a small Givi magnetic for my Sporty (and a genuine Buell for my Firebolt). The Givi fits behind the filler and clear of my legs, serves as a 'handbag' for odds and ends, rather than actual luggage. I've used larger tankbags on many bikes over the years. Don't rely on magnetic ones staying put without straps to keep them in place, as a heavy one will easily move and slide.
