Just answered the new poll, but think it need some explanation.
I have never had a jack go bad and I bought my oldest modules at the very
beginning so the must be like 7 years old. On the other hand I haven't been
patching that intensive. Done a patch or two, then perhaps nothing for a
month and so on. But I have experienced that 3 out of 40 cables has gone
bad, broken somewhere and that is also an ugly thing to track down in a big
patch.
