Where at in Raliegh? There are several fields in the area, but I would say Xtreme Kombat in Durham is the best field in the area... though I'm a lil partial Sundays from 10:00 to 3 are the best times. Pm me if you have any questions.
From my experience, you can't go wrong with either Xtreme Kombat or Black Ops. Both have great turnouts and the best prices in the area! XK is probably the closest field to you, and like Hitman said, Sundays from 10-3 are typically the best times.
Paintball Central is honestly the best place to go if you're looking for speedball/xball. It's in Greensboro, about an hour drive from Raleigh. Best turf field in North Carolina. Best competition around
