I began using the EggPin in 1993, and love the way the bass balances - however I snapped two Goetz sockets as a result of the additional torque. Not only that, the setscrews were prone to stripping out because the threads were so fine. When I was on my 3rd socket, for a while I inserted a short 10mm rod into the socket for some more rigidity, but it was kind of a pain... I talked to a friend who is a master instrument repain technician - the solution we came up with works great.
He bored out my (healthy) Goetz socket to the width of the collar, and inserted a titanium shaft - so the core of the socket is a metal rod. The shaft is drilled out to accept a conventional endpin or wheel shaft. It is very stable, and I no longer worry about about my bass crashing to the ground unexpectedly...
