PGP paintball fights, with other PGP users, is a blast! Other than that, I find that because of the awkward size (small) and the characteristic sheridan pump-stroke (quite "hard"), it is a difficult marker to use as a primary. They are still fun to play with though.
On a side note, for some reason, the little kiddies always seem to get scared if you strap one to your side or leg. I think its because they play too many video games.
