I agree with most of what was said here about the length of the touraments. My son too was almost always the final match to wrestle in his bracket and had many hours in-between matches. I don't think this is only a Liberty Nationals or Topeka problem. It has happened at many of the tournaments we have attended. Many people keep saying "That's just the way it is." I have learned over this past year to accept that, because I don't think it is going to change. Don't get me wrong, I would love for 10-13 hours at a tournament to be changed into 6-8 hours, but I just don't see it happening.
Last year there were many posts on this subject and one posting did offer the suggestion of the split format. I really do not see how this could not work at the bigger tournaments.
