.20 for indoor, limit to 350.. just to keep muzzle energy down to reduce the incidence of injury.. most of the fight happend withing a range where hopup is not material to accuracy in CQB. no downside to the lighter projectile, and a good upside in less blood flying around.
I generally use .28 or .30 for field play, as accuracy and range and penetration power is material in this environment.
I like the ability to blow through bushes that imprudent players think are effective cover.
