buddha thats not always the case but there would have to be changes,throughout paintball.
one governing body for a start.
multi formats can be run under one governing body i;e motorsport is made up of multiple formats but all are run under one banner the FIA.
as for the technical side i;e boards,etc would have to be homologated by the governing body.
so any manufacturer could still produce there,particular item but it would have to pass certain tests and rules to be allowed to enter a tournie.
the best example is motorsport where there are numerous manufacturers of parts and electronics,but all these parts have to pass certain rules and regulations.
this still allows the little guys to compete on a level playing field in theory
