Let me try to answer all the questions I see.
First off let me post this link. It's the official PBNation RPL thread. It's where you're going to get the most accurate responses to any questions you may have.
With the layout. We're releasing it as soon as the NPPL officially releases the layout. However the rumored layout was set up at Camp Pendleton Paintball Park this past weekend. I played it and it's a lot of fun!
Different then the layouts of recent NPPL's The layout will continue to be up at the park for you to play on.
The the RPL's main goal is to give players a fun way to progress their paintball careers into National Level Events they do not follow the NPPL rule book 100%.
Normally yellow would not be allowed on the jersey. The RPL isn't going to be strict on this especially since Valken gives us special blends of paint for each event. The fill may not always be yellow.
The main jersey rule to follow is do not have a jersey that looks like the referee's jerseys.
Keep in mind if your jersey designs have something incorporated into them that looks like a paintball hit, keep in mind that the referees may be on top of you constantly checking you, or perhaps even pulling you if they feel that it looks like a hit from a distance. If you have something like that on your jersey you should inform the referees before hand.
