Kuryakyn Grantour Motorcycle Bag

Hey,
I have had cortech saddle bags and they are great, but when i got a bmw I sold them, Now that I have a real bike again, I need new bags. BMWs are great if you want to ride to canada for dinner, not so much for blasting through my local roads, too heavy and tall and I hate german switch ideas.
i really dont want to scrtach or break the plastic tail by hanging bags to bounce off them.
So I was thinking of just using the Kuryakyn Grantour Motorcycle Bag and a magnetic tank bag.
I also added an escort 8500 radar deflector and the visual led that plugs into the speaker jack and a garmin 2720 gps .
Also a zero gravity double bubble with laminar lip.
I don't want to spring for a new Corbin seat, any Iron butters out there?
