I was warned about the possibility of a glassed on tail wheel possibly being the deciding factor in your tail boon snapping off in a extreme ground loop incident, whereas a skid or wheel that is intended to tear off could be the deciding factor in just the opposite happening.
I've left my steel shoe, glued on rubber skid in place, and my super faired tail wheel I made, off.
Any spinout or repair people care to comment on the idea of the tail boom slamming into the turf at a high rotation speed with a hard mounted TW.
