Nebraska format might work out good for both of these tourneys if they could work it out together, then maybe people could go to BOTH tournaments on the same day since they are so close together driving wise.

Example:

6U wrestle from 9:00-11:00 at Eudora, while at the same time 14U wrestle at Mill Valley

10U wrestle from 11:00-1:00 at Eudora, while at the same time 8U wrestle at Mill Valley.

or something along those lines, it could be a win-win situation for both clubs if they are willing to work together for it.

Either way it would mean more matches for the children on a particular day, might see more competition or might see all the same competition, but mat time is still mat time. Unless there is some rule against entering into 2 different tournaments in the same day for some reason, i see no problem with it, and would gladly enter my child in both tournaments.
