hmm, lemme simplify this for you. For an easy combo at a lower height, I'll loop 66 > 5k 2HS 6HS,HS > 66 5k 2HS 6HS,HS > (this part is kinda optional, if they're high enough) 66 > 5k 2HS 236S~D I think you can do one sequence after this, but it's really hard to get in range, but hey experiment.
there are few common loops listed in another thread, forgot which.
the most basic one you should know :
2HS 6HS HS > 66 > 2HS 6HS HS > 66 5K 2HS 6HS HS
the easiest way to practice loops, at least I found, is while learning IAD 214k.
so the loop I've been practicing just to get an idea for loops (this works in the corner).
IAD 214k \/ 2HS 6HS,HS > 66 > 2HS 6HS,HS > 66 > 5K 2HS 6HS,HS
you should also experiment with variations also, with 5k 2HS 236S~D, this should help you understand hokuto no jam's wall combos.
