I think its a little early to know which weight the good kids are going to wrestle at in any class, but its the same this year as any other year all you need to do is find what weight your kid wants to be and win.
Looking at weights and trying to see whos there and what kids you can and cannot beat is saying your scared of some one. The top four or five kids in all weight classes in High School don't back down from anybody even if they get beat. I have been around wrestling a long time and I know that coaches look at how to win a duel but at tournament time they look at each weight and try to win.
