I've always liked Shadows. I don't know why I don't own one.
Anyway, my first bike had a sissy bar, so I strapped my Joe Porper onto it.
Today, I'm in the same boat, Hal. I've got nothing to strap my case onto, and none of my cases have dual shoulder back pack straps. I only have a single seater on the Sportster, so there's not much of an option to tie the case down to the seat either. Maybe I'll build some sort of rifle holder?
I'd love to know if players with Murnak cases or other cases with the dual straps are able to ride with their case on their back
