If I don't mind adding to this discussion as a CBQ Paintball player. There are some paintball players like myself and the team I am with who do enjoy playing in the woods, but scenario play is much more fun. Our group is now getting into what is big in Europe and that is CQB. Urban environments, we are playing with limited ammo, so you have to ensure your shots count. It is also not for the young ones.
With this type of play, it doesn't matter what type of gun you are using, because your body and brain are going a mile a second. I like to think at this high level, the only difference is the "bullet". Outside of that, we probably could interchange roles and guns with only some minor knowledge to be shared.
