I was very unhappy with the Airbags and Daystar combo on the trail. The air bags just don't allow the up travel i wanted even when empty and the Daystar cradle being as thick as they are just made it worse. The Daystar cradles did allow the axle to drop away as advertised. It takes all of 30 min to put them in and take them out so I just place them in for towing.
I like that the springs are going to work for you.
