Yeah, those 3, Charge Shot 3, Streak, and of course Air Hike. Edit: Oh and Calibur is really useful for mission 20 (especially on higher difficulties)
The PS3 DMC4 board was usually more active than the 360 board. The HD collection boards are still active, so you may be best served asking questions there instead nowadays :/ --- http://img36.imageshack.us/img36/9970/rocketsnailw.gif
EX-High Roller -> Split -> Streak -> Snatch -> High Roller -> Split -> Streak -> Snatch, over and over until they die. Not very effective for earning style, but that's the most satisfying method to me anyway, you don't have to worry about timing button presses or anything.
