I had to weigh in on this one.

1. 6A and 5A are too watered down. It's too easy to make it to state when more than 50% of the kids wrestle go to state, its way to easy. So what if you're a state qualifier, it really doesn't mean that much.

2. Even with 64 schools in class 4A, its not that difficult to make it to state. A lot tougher than 5A and 6A, but still not that great.

3. If a kid goes through the season with one loss, and can't get at least fourth in a 16 man bracket at regionals, proabably means he had a cupcake schedule or he choked.

4. In most states, if you're a state qualifer means you've done something. I've lived around the midwest and lived in Ohio for a while where my son wrestled. To qualify for state, he had to place in the top 4 of his district which had 47 schools in it.
He one his first 5 matches in the state series, but then ran into some tough competion and lost his next two. He wrestled to the best of his ability, but would have to of one two more matches to make state. My point is it's tougher to qualify for state in Ohio than to place in state in Kansas. I say to the 4A kid who didn't qualify, it's tough compared to 6A. But theres kids out there with tougher deals. You didn't cease the moment.

5. I saw the Montana method mentioned. I'm recommending the Ohio format. Ohio has about 600 schools, and they divide there state into 3 different classes of equal schools.

Ohio format Solution: Combine 6A and 5A (I saw mentioned by other posters) then you have 3 equal classes. Maybe 123A has a little more or less. Yea, maybe the big class would be tougher than 4A but maybe not. The big class in Ohio is generally tougher, buy the middle class is very competetive with them. People love it there.
