Johnny - robustly issued questions, but silence when asked in return is not enough give and take.

Either you seriously want to discuss stuff, which is by its very nature a dialogue and requires a response from you, or you want to s*it stur.  Which is it?

If you have already drawn your own conclusions on the subjects of rooms and cables and you are simply using these threads to state your opnions, then: a) state your opinions b) recognise that your opinions are just that - ie they're opnions not facts  and c) expect critical analysis in return.

Folks on this forum are generally easy going, mostly with good knowlegde and experience (some with extensive of both) and they dont generally try to punch above their weight by bulls*itting or trolling others (there are obviously exceptions). If you want to get the best out of the members here you need to demonstrate these attributes yourself.
