You gotta beast mode your whip up. Like he said rocking back and forth also jerking with your lockdown to compromise base ever so slightly to whip them the he'll up. Transitioning to butterfly or full guard is always another option if he's not giving you what you want. That vaporizer from the whip up less 'old school' is not going to help his situation on anyone with solid base. Next time I roll my mom I'll definitely give it a shot, she might have too much base as well though.
