Best practices for moving gliders around?

Stacking the hangar...

Staging...

Clearing the runway...



I've recently been told that the Europeans never move a glider by the wingtips, but it's almost a necessity when stacking our hangar. (Gliders are on wheel sleds, so the load is not high.) Things can be tight and we often need someone on each wing to prevent hangar rash, but don't have someone as a wingroot pusher.

There are some significant some differences of opinions due to various culture and practices differences from previous clubs. So, what does your club do?
