I would be willing to bet that there are more (heavy) 8 year olds than 40 and 43 pounders combined. IMO the state could easily eliminate the 40 and 43 pound weight class and add a HWT division.
I would be curious to know how many of the kids at 40 & 43 were actually 7 & 8 year olds. I would suggest you research the last several state tournaments. This might help your arguement.
Year after year a debate begins about 6u kids being allowed to wrestle at State. I hear comments that "they do, they can wrestle 8U". Typically, the only 6u kids that benefit are the little guys. Why.........because they are wrestling 6u kids. I'll stop with that...I'm about to open up a whole new thread.
Good luck !!
