How does Perfect Game Academic Showcase compare to Headfirst? Am I mistaken in thinking Headfirst has been doing these longer? I know both have excellent reputations, but wondering about this one area in which they "compete" for the same players.

I won't address PG, never attended a PG event. I will tell you that Headfirst helped my son greatly. I recommended them to others and they were very impressed. Alot of interaction with the actual coaches from the various universities.
