Arkenstone -- more field variety, but would much rather play at Nitro
Various others no longer in existence
I have recently played Arkenstone and Nitro. Nitro is my favorite. The staging area for the woodsball and speedball fields is centrally located, allowing you to easily make it back there and rest without your mask on between games. The breaks are a little longer than normal, but this just gives you a chance recoup and cool off....especially useful when it is 90+ degrees with 90% humidity (especially nice for the older guys.....I have been playing paintball since 1987). The woodsball fields offer some very thick underbrush, allowing you to sneak undetected around your opponents flank. The prices are great and you can bring your own paint. Above all, what makes this field top notch is the staff. Mario and company try exceptionally hard to make you feel at home. I have played Nitro twice in the past 3 months, and plan on playing regularly from now on.
