I'd like to request a thread from someone who knows what they are talking about. Aside from the overdone - what woods should I use etc. what is it when you are looking at a particular piece of wood that you are actually looking for?

I would like to know - how to tell if the wood will remain stable, common faults with wood, things that signify the wood as good for building with and things to avoid

Yeah, even though you said you don't want the wood thread, everything you asked for is in the first post.
