Why not weigh-in at the table? Give a pound for the shoes, head and singlet. If the wrestlers make weight then wrestle. If either fails that wrestler loses.
Hydration testing has to be very costly and it does not eliminate DEHYDRATION and CHEATING.
Scales are not that expensive for the tournaments each team could bring one or two.
Satellite weigh-ins at your own school days before or the morning of is BS.
Just think of all the hydrated kids we would have and the excitement. The crowd would be part of the weigh-in process.
I would enjoy watching a wrestler suck down 10 or 12 pounds and NOT rehydrate and wrestle a quality match.
