If it really comes down to it, take a survey of all the weights of the male athletes in High School right now (Fr. So. Jr. & Sr.) and graph the data showing weight ranges from:
90-100
101-110
111-120
121-130
131-140
141-150
151-160
161-170
171-180
181-190
191-200
201-210
211-220
221-230
231-240
241-250
251-260
261-270
271-280
281-290
291-300
I say athletes because they are what we are researching not the band members, drama club, science club, people, we are looking at the athletes. You will find a bell shaped curve that should land in the center somewhere around 145-160 lbs, as that is how the world works, you will always find more kids at the middle weights than the upper & lower weights because most kids are in the middle of the bell curve.
The reason for more lower weights is kids grow into bigger weights not shrink into the lower weights, so why not have more steps to get to the top than giant leaps to get to steps at the upper end. There needs to be more weights in the middle with more lower weights as kids are growing coming from sub 103 and growing upwards.
A 10lbs or 15lbs difference to a HWT is nothing, I mean honestly they can lose 6-8lbs a practice if they push hard enough for a little guy 3lbs is a HUGE practice so a 7lbs or 8lbs weight differential is needed or less even, thus the smaller weight differentials at the lower end, and more weight classes as they are needed.
On the note of adding more upper weights will add more kids to the wrestling room, you guys are the same ones saying we don't need the lower weights because we don't have the kids to fill them, it's kinda the same philosophy, just because we have room for them doesn't mean they will always get filled. Why not provide opportunity to kids who have no other opportunities instead of catering to only a handful of athletes?
As it has been said already most 103lbs kids are eating to make weight, why punish them even more by adding another 3-4lbs to the weight class? Also how many Heavyweights cut weight? How many teams are stacked 2-3 deep at HWT? Most teams have multiple 103's due to the nature of the Freshman classes and wrestlers maturing as they get older.
Maybe I'm way off, and go ahead and shoot holes in this, it's just my own opinion.
