I guess I'll keep the rough ones I'm using...
That last sketch should do well for you!
It certainly looks a lot simplier than the one you started with huh?
Tell me about it (re cost) it's certainly way more advanced than the stuff i did on here - it seems to have achieved its purpose - so thanks for all your help sorting it out --- to look back at what i started with seems a little stoopid now - tad embarrassed, I guess. but there you go.
Thanks again
