The whole argument comes down to numbers. 4a has more teams and more wrestlers than 6a and most(not all) of your athletes in 6a have more choices about sports oppoutunities. I was a 4a wrestler and I am now a 6a assistant coach, both have there advantages and disadvantages. When I was a high school wrestler I thought 4a was tougher but now I can not make a judgement. THe lose/win ratio is of no answer and bickering is useless. I say look at the good guys in all divisions and lets have a Grand State tourney again to decide who is the best in the state regardless of classification.
Just a thought on how everyone could be happy. Or even better lest just combine them all, like freestyle nationals and make it a 4 day or 5 day tourney!
