214D > Dash > 2DD > j.C > j.2C > Land > 2DD > j.2C > j.DD > j.214D (~5000 DMG)
New combo i found out, a variation of Tsuakasa's neutral jump combo shenanigans with a 214D launcher. Works great even if 214D will hit at maximum distance, you'll just need to dash a little longer.
It's way more damaging then 214D > 5DD > 6DD.... , the only tricky part is the dash.
Further exploring the 214D launcher i found out you could easily do the nasty 7500 DMG combo you usually get from 214D~C, as with the previous combo it all depends on the dash.
As you can see, http://www.youtube.com/watch?v=bQ6ufUBYoMw (214D > Dash > 2C > j.C > j.2C > j.C > j.2C > j.214D > RC > Dash > 6C > 6DD > 2DD > j.DD > j.2DD > j.214D) , it's the normal 214D and does the same amount of damage as if it was a 214D~C.
Just my two cents, I'll bring new stuff if they'll come to mind
