as to you oz. the real answer is at 6-8 there is a major difference in that age. now as freshman they have all those years that they have wrestled and are able to compete with the upper classmen. maybe some of the lighter weights at age 6 can compete but most of them are not able to. ask any of the coaches and there are a few kids that can compete with the 8 year olds but majority there is no way. Im done. somebody else can talk to this brick wall.
