1. I don't think your solution will work as kids will just cut hard for the first weigh in as they do now for certifications. There will always be a way around this and the dedicated will cut no matter what. but by making it illegal with heavy penalties, all but the truly dedicated will stop, those who are truly dedicated will cut less weight out of fear of being caught, it would be very hard to hide the fact you are sucking 20 pounds.
2. from personal experience a lot of kids I tried to recruit mentioned the singlet as a point of contention, many even made fun of it, you can imagine the politically incorrect insults levied. Even some kids making this suggestion made those on the cusp question joining. I think the singlet is a self-inflicted wound we do not need. Not to mention the fact that a lot of wrestlers don't even like wearing them. For those who are self-conscious or shy about their body, this is a hard aspect to overcome. Personally, I didn't join a team until 7th grade because before hand I was too self-conscious about the singlet
3. the tournament issue is a little more abstract. I suggested 6 hours but anywhere from 4-8 I think is acceptable. I remember waking up before 5 am and getting home at 10 pm, sometimes later. Of course, i was dedicated, so it didn't bother me as much, but all of my teammates found it miserable. Many even would try and come up with excuses to get out of going. At the time I thought of them as mentally weak, but I now realize that was foolish. Most were doing wrestling as s second sport or just to get in shape, or because they only kind of liked it. They didn't have the same passion for it as me. Had I played another sport like baseball or lacrosse just for fun and the tournaments had been as long as wrestling ones, I would have quit immediately. No Hs kid or parent should be forced to do this. Of course, those kids going to nationals don't have an issue with this, but the kids who are just going to some small hs tournament shouldn't be there from sunrise to sunset and later.
4. 1 - 2x a month is fine. More emphasis on dual meets. fans like them much better, sports are about the fans too.
5. 2.5 is way too long. I think ideally 90 minutes is good, sometimes going 2 hours. Wrestling is hard most kids don;t want to go live for over an hour and then do conditioning. Hs sports are about having fun before they are about winning and getting a college scholarship
6. I stand by two days off. Six days a week is a lot when you have things like homework, SAT prep, clubs, family responsibilities, part-time jobs, and maintaining a social life.
For those that think my suggestions are all about making wrestling easier when it should be about toughness and hard work, I hear you. But I think you should reevaluate whether the goal is to produce national champs or about growing the sport to include all kinds of kids and creating a fun, positive environment for 13-18-year-old kids to learn and grow, and making lasting friendships.
