Ross, I'd like to know the answer to that too, we've always had issues with Eddies weedy arms getting the damned thing in and out of the sock.
In answer to your other question re controls etc, the answer is that we led everything to a position where we can both do it. Its not ideal but it works, I found it I put enough purchase on kickers etc so Eddie can use them, we run out ouf travel all over the place.
