But can be surprisingly "sloppy" on some trailers.



John Murray at Eastern Sailplane has had 50mm balls for a long time but
not at this price. I've seen one (Blanik enclosed) trailer That would
not fit on a 2 inch ball. It was 50mm or nothing. If your trailer is
designed for 50mm, maybe that's what you should have.
