Why not eliminate pre-registration? That way you sign up at the event, weigh-in and 2 hours later you start wrestling? Seems with Trackwrestling over the last few months that is that has been happening anyway with the problems of scratching before a tournament. End registration and weigh-ins at 8:00 am and plug all the names into the system with random draw and be ready to wrestle by 10:00. Sounds like an easy fix to me.
