I don't usually comment when I downvote things, but will be downvoting this tomorrow unless I get run over by a bus.

It's all true, I don't disagree with a thing the OP has said, however I see nothing at all new or necessary in the post.

I'll be interested to see if I'm way off on nodes to consider (level 5/6 and above i think) in a couple of days, I may be...

Maybe its a reaction to seeing the same thing come up time after time after time and newer people will disagree..
