I agree that its worth at least experimenting with at the elementary and MS level to see if we can get kids hooked, even though they may make the switch to a singlet in HS.
However, (I know I'm halfway jacking the thread) it will be hard pressed to get most of the Middle School programs in the state on the same page with allowing this in competition until some type of state level MS wrestling organization if formed within the IHSWCA, IHSAA, or otherwise. As it stands there is already such a discrepancy across the state on the number of weight classes, the weight distribution of the classes, the period times, allowing for a weight allowance, use of equipment like headgear, etc. Some districts or school conferences at least have some general guidelines, but they sometimes vastly differ with the neighboring area. As such, I'm not sure where some of these schools refs or coaches would come down on a major uniform change if the opposing team showed up expecting to wrestle win compression shirts and fight shorts. That is at least until the IHSAA decides it fitting, and it trickles down from there.
