well the alternating grip is pretty hard to pull off. I can throw only throw it once and i just cant get the timing right from there but if you notice that they don't run at all when they do the alternating grip. Thats for the one where they just walk in a straight line and keep throwing the grips forward. For the bak grip you have to have perfect timing. The second you do a back throw you have to hit the grip button. That might help some =3
and also you should try to get the meteror smash grip in. its great for those grips you get at the edge. When popo grips you do a jump f att (which will trigger the foward throw) and with good timing you can get a meteor smash in with nana.
and with some practice you can desync them with 2 flicks on your joystick so that you can get some alternate atts going but its really hard to pull off and have full controll of what each character does but with some practice you might be able to come up with a nice long seriers of buttons that can be really affective. But keeping the desync going is like a pure offensive strat since I find myself spamming att buttons just the keep them desynced
well you need to not say "go at it" when you want to fight cuz thats not what i think of when you say that... yeah ok ill be online quite abit this up coming week lets make sure to play!
