Brian,
with your 3 grobs....tailwheels isn't the only damage done by dragging around with wingtips.

Put a person on the nose to press down with a hand while taxiing. This will lighten/float the tail around the corners. It also prevents overrunning ropes, rolling ahead to strike anything. Better use of two people on the glider than one per wingtip.

This becomes more necessary when you stick a tail dolly on her.

Dragging by a tip for a heading change will eventually require replacement of dragspar fittings and bearings. $$$. On all/any gliders.
You wouldn't want to yank your grandkid by their wrist, knowing what stress that will make on rotator cuffs for later years. Same principle.

Just sharing, not hollering. Meant for the broader audience.
