I agree with you on this, I show my builds only once per show win or lose, then after they have been to all the shows for the year they are retired, if they go to the same show again, I put a sign with them "for display only". I have seen the same build win multiple times at the same show year after year, and this does not seem fair to the other builders, in fact it discourages most of the people that I have talked to about it. So to answer your question: BUILD, SHOW, RETIRE. That's the way it should be.
