In no particular order:
1. Music: Scrap the usual (sorry Queen, but your time is up). Go buy Carl Orff's Carmina Burana. Movie soundtracks are also really good in between rounds: Batman, 300 and the like.
2. Heartbreak Round: Best 3 hours of wrestling at any big tournament. Don't let the luster of the finals fool you, boys become men in the consolation semis.
3. Random Draw for the Finals: Why not?
4. Senior Recognition: During a break on the second day, bring all the seniors onto the mat and give them a standing O. For most of them, it's their last day as a wrestler.
5. Put teams from the same league in the same locker rooms.
6. Have a place set aside for wrestlers to cut weight on Friday night. A side mat in a empty gym is ideal, also, have a good check scale available.
7. Offer a 2-day pass on the first day at a reduced rate.
8. Have paper & plastic recycling bins, for empty water bottles & unwanted programs.
9. Put big trash cans in the locker rooms, the usual can is not capable of handling that much shoe tape.
10. Make sure ALL lockers are locked/empty & ALL other equipment is locked in a cage. I've seen locker rooms that look like war zones after a 2 day tournament.
