Another idea just for smaller invitational tourneys would be to change to all round robin formats. I have had my son participate in these in Iowa and Nebraska. They limit the number of kids, group by true weight in groups of 4-8, and have the rounds accordingly. My son wrestled in the biggest tournament in Nebraska this year and 6 kids in his bracket, wrestled 5 matches, we were wrestling almost every 45 minutes with 3-5 weight classes assigned to the mats. The tourney was split format with 8-12 wrestling from 9-3, then the older kids and an open division wrestling from 3-8. They had about 1100 kids and it went really well.
