With kula, i found that rapid fire A technique. Who wants to know it..... lol
Press A first as you cannot do it off the first A. During the first A, press A+C+D, A+C+D then repeat, you can get an easy 10 hits which is great after sC, f+A, (B+C) A, A+C+D *9.
Its very easy to achieve so it should be staple in combos from now on and adds great damage if you just do it followed by crouch B, sB, f,d,df+C or qcb+B+D, qcb+B, f+B, f,d,df+C (corner).
I have not experimented on this move as to see how much guage it fills.
Enjoy kula fans.
