From my experience last year:
1. The refs were very good, yes some calls were bad but that happens in any sport. I was once called out on an imaginary hit which sucked but you don't hear me moaning
2. Although the turf was not on every field last year, I had no trouble playing on grass. Take sports like tennis, the players have to adapt to different surfaces to play on, the fact is its the same in paintball, whether it be turf, grass or whatever they throw at you.
3. Scoreboard...the only problem i saw with that was that the M was in the way if you were sitting in the middle...big deal.
Okay im finished ranting!!!
EDIT
Does anyone know the exact location of the beach?
