I've been trying to come up with a new combo using an rapid cancel. So far it's
[5a....]6c, j.623b, RC, 6c, j.623c (for about 4k.) or j.623b, land, 5b, 6c, j.a, j.b, A shuriken, j.C (3.5-4k)
I've gotten the 5b to 6c a couple of times but the timing is waaaayy too strict. The 6c to command throw is pretty decent if you just want to surprise someone with it. Also, if you wanted to daifunka right after the RC or after the second j.623b, just delay it for a split sec or else you'll just run right past them. This pretty much works for everyone except Rachael, Carl, and Noel. You can hit this against Jin but you have to have the 6c as the first hit.
Oh, and I've been having trouble landing the triple crash combo. After the d.2b, I can't seem to get the 623b to hit, any help?
