Have you read the Opti rules? <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" /> They are crazy complicated, right down to construction laminate details. Sometimes the simplest rules create the most complicated classes and the goal of a simple class requires the most complicated rules.
On that note, may I suggest another possible addition to the rules. A clause along the lines of "If it is not stated in these rules it is allowed/disallowed."
