I care more about stalling in the game itself than on the clock. I never consider the motives of my opponent in clock use when considering my moves. I move according to board position not clock time. As far as stalling in the game or otherwise defensive play, I play only the open variations now. That eliminates the defensive advantage which is big in the volcano variations.
