If you certify at 130lbs. you can't go down to 125lbs. for regionals(no brainer)but I don't think you can wrestle up a weight class unless you make weight at the lower of the two, I think that is what they consider breaking. I think in order to wrestler at 125lbs. at regionals you have to make 125lbs.(127lbs with the 2lbs. allowance) every time.
Does anyone else know for sure?
