19 weight classes is Outrageous for 5 & 6 year olds in comparison to the following tournaments & their 6 & U classes. I cannot fathom that there are (16) 5 & 6 y.o. that weigh 125 lbs in the State. Your talking about complete 16 man brackets.
Tournament examples: 6 & U Only USJOC: 37-66 + HWT (only 1 in HWT): 5 entries in 66 [10 classes] Tulsa Nationals: 37-60, LT HWT 61-70; 71-Up HWT [10 classes] Rocky Mountain Nationals: (Monster Match) 37-74 [9 classes] Big Horn Nationals: 35 - 40 - 45 - 50 - 55 - 60 - 65 - 70 - hwt.* [ 9 classes ] I guess I could keep searching but realistically the 8 & U weights are not suitable for the 6 & U wrestlers.
Moreso interesting would be the identification of the attrition within the 6 & U group that does not make it past 1 month of practice because its not WWE or how many only go to Novice tournamnents throughout the season. The $$$ cannot substantiate the potential loss within this group. More review apparently needs to be done in regards to the weights as I'm sure most of the 40#'rs in the 8 y.o.'s are truly 6U.
