It sounds like you definitely have a good handle on pistol play as it is, the only thing I would say is that instead of taking advantage of the initial rush and then being "patient"...always be moving. Take 2...maybe 3 shots from one location and then move. Obviously if you have an incredibly adventitious position, hold onto it, but usually recball doesn't have those spots. Just always be moving.
Another idea I've got for you is to find a heavy to pair up with. On recball days it usually isn't too hard. Find someone with paint to waste and use them to cover you. If you can get a heavy to keep the OpFor's heads down and behind bunkers you can cover amazing amounts of ground in very short periods of time.
