Heavy weights are hard to find in 8 and under. My son is one of the heavy weights and we have to ask every week if there is anybody for him to wrestle at the tournaments we signed up for. I do know that there is a good 8 and under heavy weight from Concordia, and Ottawa my son has wrestled them both, and took him to the 3rd round.
We did ask once were all the heavy weights were at 8 and under and we only received 1 response. So I am not sure if there would be a lot of response like was stated previously.
