Since my son was asked to do the Team One West, we've been looking into BF events - and boy the sentiment here is mostly negative. But having talked with a couple of families who took part last year, he is going to do it. They had great experiences, and both the boys received recruiting interest. My son isn't a "top 200" kid, and that's who I have been led to believe the PG events target. That said, he has gotten interest from a Headfirst showcase he did last summer, and we anticipate more as this year, his junior year, ends.
Good luck to your boy!
