But Johnny joints use urethane bushings in exactly the same manner that everyone here is complaining about. It is a metal ball rotating in 2 urethane sockets. All the wear problems and sticking problems of urethane apply to them too.
Besides have you ever held one in your hand? They are freaking massive. A 9/16" JJ is almost 10lbs and larger than my balled up fist...and I have huge hands!
