My controls: c stick set to attack, x and y set to special(never used), left trigger set to jump, tap jump off. I find this control scheme to be the optimal way to perform double stick sh aerials; tilts and aerials in general are optimized cause I don’t have to worry about changing my aerial momentum when performing them. In particular this has greatly helped my ability to spike since I never accidentally fast fall when performing a dair. This control scheme also minimizes the amount of distance your fingers have to travel, especially if you learn to nair with the c stick(hard but once you get it you will never go back). I essentialliy use the a button to smash attack and jab occaisionaly. I really think this is the optimal control scheme, would love to hear some feedback on it.
