PBR States definitely differ. I wish we had the events/organization/leadership and quality of the PA/NY events. Our experience with PBR TX was not all that (quite bad at the various events and 2 showcases (10 pitches only, and they got the type and velo wrong). Additionally they don't even update velo for pitchers (even when they (Tucker) tweet about the updated velo) and getting on/to Future Games might be more political than you might think, but if you can navigate it. Great event. Great exposure. Just be careful putting your eggs in showcase baskets. If you're going to stand out, great. If run of the mill, then skip. Head guy for PA/NY is great. @DanCevette is also a great one for your kids to follow as he offers great insight and inspiration almost daily. I talks the talk and has walked the walk.
What about a connected 3rd party? I'm not saying pony up for a recruiter or service. But what about investing in a Radar Gun (NOT pocket Radar) and getting video for email/youtube that you can share? If you have a video with a radar gun like Stalker Sport or Pro 2 or higher - way more credibility and now you have it for every event, every video for tweets or updates to a coach? What about a local photographer that has video service or promotion available and now you have a tweet or @mention to list in a baseball profile you share?
Why so many showcases? Do you have something to showcase? If you don't you shouldn't go. What if you have a bad day, now it's documented and you paid big money for it ($700 for PG). They do the same thing as all showcases whether academic or otherwise. Heard good things about Headfirst and some other academic showcases.
Are you not in an area where you can get to a BIG event? PBR/PG? More opportunity to be seen by more coaches (live or video), less expensive. A good travel ball program, going to a good event and competing, is better than a high $$ showcase.
What about an academic showcase - if you have better grades? Grades/Test scores matter. These showcases brag on who is going to be there, but they hardly ever are and with the extended dead, they haven't been or can't. More access via video for an appetizer, but coaches want/need to see you in person, usually.
Be careful with camps too. Some are good and better than others and others are just not. Plenty of threads and information on here to check out.
You also have to get to the region you want to target for schools for events/tourneys/showcases/camps. We had to get east to target east programs that wouldn't come to TX. Be selective on what and where you go.
