You can get a lvl 2 j2c off of 6b counter hit. 6b sj9d j3cd then do what you will with it. You can go right into bbl or 5b jc2d j2c bbl if you're sitting on the wind. It works midscreen but is much easier in the corner.
edit:
After playing with 6b some more I've concluded that it's much more practical to do a winded dash and pick up with 2b 5b and follow up with j.c jc2d j2c. It's still cool that you can do it but I feel it's only real use would be for combo videos.
Here is wall bounce BBL setup that works on OTG frog characters.
5b > 5cdc > 214a > dash > 3c > 236b > 5cc > 236b > BBL (1 wind, does a little over 3k)
I think my problem is doing to the j2c too early sometimes... I'll just keep plugging away at it and I'm sure I'll build consistency. Thanks for the advice!
on the combos using j.C > 2D > Lv 2 j.2C is there supposed to be a jump cancel in between the 2D and the lvl 2 j.2C? for example J.C > 2D > jc > j.2C I use the jump cancel when I do it but it doesn't always score the lvl2 j.2c.
just an fyi, 236cd at the beginning of that match beats an arakune that likes to double jump backwards and throw out a cloud. I usually spend a lot of this match knocking arakunes out of the air with wind/projectiles.
