Ultimate Paintball is quite a nice field with a great staff. Regulator's Outpost's refs were disappointing in the college tournament in which I played.
Dynamic Games in Winder, GA has a new field that is great. The staff, including all refs, are excellent; they all really know what they're doing. DGS is a great place to bring new players because the rental gear is so nice. Paradox, the field team, is getting extremely good, and they're great gun techs and refs for us college/rec. players. DGS is still working on a second speedball field and woods field that will be huge. George also has some of the best prices around. I drive about 60 miles one way to go play there. Check them out!
