it sounds stupid, but 8pp2p works surprisingly well in tag.
It might be like Kasumi's BT 2P where it allows a nice relaunch.
33pp relaunches as well like it does in DOA4.1
it can be used in the middle of the combo. 8p pushes them higher, so you can get in 2pp and then tag in your partner. i've frequently done it, tagged in my partner, they did their thing, and then i was able to use it one more time, and then finish the combo with the tag partner. it's stupid, but it works. At least in the 360 version.
