sooooo, I dont play carl, but I was messing up w him, and noticed, you can actually stay in the air a long time just doing j2C, maybe it serves as a weird mixup tool on the corner, just keeping the player blocking high, and hitting low w nirvana.
if you use j2C>jA(Whiff)>j2C you can use as j2C's as the jump it self lets you xD
I dont know if you already knew that, im pretty sure you guys do, but i havent seen anyone use it rlly.
*** just noticed j2C isnt an OH :V
