the guys there are more serious than those who go paintballing
It's just different approaches with different goals for the sport.
A mate of mine used to play pro paintball and moved to airsoft because he was getting a bit old and he likes the toys more. He can still out shoot almost anyone on site, his snap shooting is awesome, as you'd expect from paintball. You get a certain amount of 'people' who feel closer to real soldiers because they put on the gear.... each to their own i guess.
