I usually like to limit a conflict to one type of stress, that of the main focus of the fight. If it's a gun or fist fight, that's physical, if it's a discussion or some weird spell, that's mental, if it's some negotiation or something similar, social. I only allow actions that don't fit that type to be maneuvers to aid the main actions.
However, if you want to have a snark off in the middle of a fight, we can pause and switch to a social conflict real quick, solve that and depending on the outcome, get back to fighting, probably with a benefit for the winner of the snark off.
