Then the answer is, each in its own time. When December rolls around, mine starts thinking H.S. When H.S. is over, it's time to lock in for the Academy homestretch. Which is why I have said, repeatedly, kids should be allowed to play either, neither or both, and the coaches/trainers should do their best to facilitate it happening.
It's not an either/or, until so-called "adults" get involved.
