It's fairly academic when it comes to most GS's as the cross-over straps don't deal well with handguards (well those like the OE 1100 aren't a problem but the type that fix to the bar-ends are).
I've used the cross-over straps on all sorts of bikes. Bikes with bars mounted on aluminium sub-assemblies are the best application.
I have transported my own bike and used cross-over straps but we have a modified set with a slip-loop so that the strap comes up against the clamps and then through the sleeve. The main downward force is then across the headstock and not through the bars.
Two straps through the rear footrest hangers on an 1100/1150, angled forward and out, with the front wheel blocked is usually enough (provided the suspension is slightly compressed). Any other straps should only be needed to stop any lateral motion.

I did manage to get a price from the UPS website, which was about $250
- I guess either they or I had made a mistake. 
I could understand if they'd been in a crash.
