switch and nollie hardflips.
i used to try them all regular with my popping foot on the very corner of the tail and flick it around as hard as possible, all wrong. put the popping foot flat, 90 degrees to the board covering half of the front bolts (for nollie) and just let it unfold. definitely a trick that if you try and force it, not gonna happen. if you find the sweet spot, it's minimal effort for sure
