I agree. There's also the matter of HOW you whack the pole.  Many years 
ago, I spent time on a service bench fixing things, and later spent time 
doing field service.  Banging on things can be a good way to find 
intermittent problems, but HOW and WHERE you choose to do your banging 
can be a bit of an art.
