for orbs what I do (which happens to be good for orbs)...
jB, B
jC, 3C (I find it more consistent then jC to 5C)
6A, 3C (non-CH, can be difficult to tell when it's CH or not, I usually assume CH)
B/2B spam...
I've never really had too much of a problem for orbs TBH. I just wished he started off with 2, as it's annoying to have to wait around for the 2nd to come up to start looking for 214B/623AA combos.
If you land jB, B, somewhat early on you will *likely* generate enough orbs to go straight into 214B/623AA even if you started the combo with 1. I haven't tested this out that much, but I know that I have done the combo with 2 orbs, spend it on 214B/623AA, but end up with another orb left over anyways. So apparently between what fractional orb I had generated prior to the combo, the meter it gave me for doing jB, B, and the time it took to complete the combo, I got another orb.
