Tie downs for passenger seat?

[copper]

I would like to carry a duffle bag on the passenger seat and use one of those stretch cargo nets to hold it in place. Has anyone come up with a method to attach the hooks somewhere without damage to the bike?

I picked up a pair of Rok straps. No hooks, easy to use. I'd recommend 2 of those for your duffel, tie them on to the passenger handles with Rok straps.
