Wrestling up an age group in the state series gives the older kids an unfair advantage. If you feel that way why not just eliminate age groups entirely. That way all the kids would have the same disadvantage against the 16 year olds. See how that feels.
Lets stick to the issue of having age division appropriate weight groups that meet the needs of the athletes. Wrestling up is not a solution when it is not applied to everyone. Plus it might just open up a whole new can of worms in other age/weight groups.
