If you are so bothered about unity, wouldnt the fact that there are conflicting series around the world all running different formats be more of an issue to a wider audience than slightly different rules. The rules are largely the same. You are hit, youare out. Cheat and get penalised.
many of the busier men you talk about, using politicians as an example are paid and employed purely to debate things round a table. How often do conferences and such end in stalemate.......Israle vs Palestine....IRA vs GB Government......Koyoto Protocol..........G8 summits...... These guys are paid to debate and often they cant agree on anything other than that they should afford themselves a pay rise.
Figures in paintball, Laurent, Niall, Manfred, Pedro, Hatts, Russ to name the ones you are talking about have busy lives with their own businesses. If they had endless time to attend meetings then i would agree with you. But they dont.
I genuinely do not see any problems with the things as they are in regard of separate rule books. Its not as if they are that different anyway, a phrase here, a word there. Its not as if in the MS you can play on when you are hit, and the PA you cannot. If there were major changes then maybe something should be done. But there is not, so there is no need to.
I marshalled and played in the NPPL, the Millennium Series 7 man, EXL Xball, Dartford 7's (PA rules) all of which have slightly different rules. I had no problems as a player or judge, and that is playing 4 different series'.
