Finally, my last bodge for now is to deal with same issue described by Clarion, to get a Saddlebag to sit a bit more vertically and away from my legs when using saddlebag loops
It's some foam pipe lagging, shaped with scissors to fit around seat post, and some vecro running though it to secure it to seat post quickly. Not pretty but does a job and weighs nothing. Insulation has some DUCK Tape wrapped around it to "beef it up" a bit.
I found the Barley hung at quite a steep angle before (when it strapped directly to the seat post) and it swings about too much for my liking if it wasn't secured.
