Thank you Spencer for offering to take on the role of moderator. Hope you can do it. It's quite a job ahead of you. For my 2 pesos worth, I would follow the old KISS philosophy which is "keep it simple stupid". It will be difficult enough getting all that matters on track without adding complications and variations at this point. I'm sure improvements can be made along the way, but, if it's not broken don't fix it...for your own sake.
