I did not read every post on this topic, but there is a difference in tourneys and agendas of each and every program.
We did try and get all the annually-strong programs into one league to where we could beat up on each other during the week - it was called BBI Premier. I can't remember what year we started it, but it consisted of DBAT, Tigers, Cats, Blackhawks, Patriots, Panthers, Lake Highlands Wildcats, etc. The only perennial power that wasn't in it was the Dallas Mustangs, they played in Lone Star. There were probably other programs but I can't remember. KCR might know he has a much better memory than I do.
It was a great league and we had TCU, LaGrave, UTA, etc for our fields. Every year we existed we had one team, if not two, make it to the Connie Mack World Series. It was great.
But as you would expect, things happened between program managers. Egos, backstabbing, etc. We all couldn't stay focused on the big picture.
And as far as tournaments and where you play etc... I can tell you that our 17u team plays in a Houston Invitational annually, where specific teams are invited by the college coaches themselves, and we play 5-6 games - and every game is at Rice, UH, and San Jacinto - but they are the coaches inviting us. Cost is only about $675
On the flip sidethere is a great 17u Showcase in event in La Grange, TX (if you know where that is) and they use Columbus HS and Schulenburg HS as well and we are in the middle of nowhere, TX and there is always 75ish college coaches there. We handed out 46 rosters at that event just this past summer.
Its not necessarily the venue by any means... scouts follow the programs, not the venue.
Just my opinion though.
A summer league of all quality programs would be great, just not going to happen IMHO
