Has anyone compiled a list of guaranteed reversal or throw followups - eg. which allow ground attack, which allow ground throw - and the likes? Also, are the "guaranteed" ground attacks side rollable out or not. And if done against another Aoi, are they reversable by Aoi's ground reversal? That's actually another question - is the ground reversal actually useful for things? I have never seen it used anywhere. Or is it just better to side roll?
