Organizing transportation details for all of your necessary gear for a gig is not a universal, one method meets all needs, protocol. When I contract for A/V services I have found the most reliable protection for all of my critical gear is with hard shell enclosures that offer better grips and much less worry about stacking damage. I travel with a Ford Expedition SUV & when needed a Trailer with a KV2 ES system for FOH. There is no way I could accept the risk of a soft bag to protect my SQ5 desk for this scale of gear transportation.
