I do a similar thing where I drape the loosely rolled wing over my drying rack. Hanging overnight is usually enough to dry the dacron, handles and bladders.
The canopy usually dries while I am getting changed and packing my foil.
My last few sessions I have left the strut clipped and deflated the leading edge. I can bunch the wing under one arm and carry it with no risk of dropping it in the sand or getting water in the valve. The deflated wing sits fairly well on the grass to dry. I'm not sure there much benefit in leaving the wind inflated while it dries. In between sessions I eased the pressure in the strut but did not deflate it. That's enough to stop the retracting strut bladder without making things a pain to deal with.
The North Nova has strings attached to the front of the strut bladder to secure it. The Wasp V2 has a zipper at the front of the strut and places to secure the bladder so it doesn't fall down.
