This is where I think your logic is flawed. You assume that if you class wrestling, that more kids will be exposed. However, it has alot more to do with expanding the tournament that is getting more kids exposed, not classing per se. If we went to a 2-class system, that's double the state participants we have right now. Just expanding the tournament would have the same effect, as far as exposure is concerned. This is assuming that the IHSAA, with their infinite wisdom, decide to stay with the 16-man weight classes for state of course.
On top of that, I don't care if we had 5 classes, college coaches aren't flocking to Indiana to scout out wrestlers. If you want to be recognized, you hit up the national tournaments and get your name out there. Even Y2's admitted to this. They're probably only a couple of state tournaments in the country that can hold any value to recruiters, Ohio and Pennsylvania. Even then, I'd assume that kids from those states still need some national events to add to their resumes. So kids, if you really want exposure. Start writing letters to colleges, hit up the national events, and make a name for yourself.
