I will say this about wrestling heavier kids. my son is one of the 10 and under hwts. this has been my experience. we have wrestled up in age for two yrs. not a good deal. both times i put him in this situation, he had to face kids a fooot taller and more proportionate in weight to their age. it was a bad choice from an inexperienced parent. in his normak age division, we have given up 30 lbs and been beat real bad having 30 lbs on our side. the smaller guys have an advantage. they are faster and more agile. just because a kid has 30 lbs on another kid doesn,t always mean the have the advantage. we must teach all kids to know how to wrestle the lighter kid versus the heavier kid. I would not bracket 130 lb with 170. that was a big mistake. if you are hosting a tournament in kansas, you should know better. i do believe the 10 and under rule is 20 lbs maximum. 8 and under 15 lbs maximum. unless it is agreed upon by both coaches.
