Great questions guys. You have uncovered the reason it is difficult to put on a clinic. Paintball is so specialized these days, that the higher level the instruction, the more focused the lessons need to be.
If the Canes are running a clinic it would make sense to me that they would teach what they do. National Level Xball. A clinic such as this would resemble a Canes Practice.
You would learn what kind of equipment you should be using, how to warm up, how to drill. You would learn an assortment of drills that will help you improve your skills. As well as experience game play at the highest level and intensity. You may have played against the Canes at the NEPL, but you have not done it with this level of attention to detail, and expectation.
In my experience, when we did this in the past, the reviews were not the greatest. Players complained that it wasn't as much fun as they thought, or that they didn't get enough actual play time. I laughed at this.
We promised to put them through what we went through, and we did that. they were right, it is not all fun and games. We worked hard, and they worked hard. If you have played any organized sport you know. Practice is not just scrimmage. Drilling is the lesson, scrimmage is homework.
I didn't mean to go on a rant, but that is what happens when I get started.
I figure... If you want to play high level Xball, you find a high level Xball team and have them show you exactly what they do. Then you go do it.
Maybe I'm just simplistic.
