Dan,
Maybe I've heard it too many times this way at this point but I don't hear any problems with chord structure. Altho I understand the limitations you're talking about and am by no means an expert on working out everything exactly the way I want it on every song with RT's yet, I'm overall happy with the way this one turned out. That's not to say further tweaking is out of the question. grin.

Thank you for your comments. I appreciate your thoughts and kind words.
