what sessh meant to say was 2H RC fafnir, dash 5S, j.H, j.D, dj.H, j.D land 5S, sj combo/dust loop. you're looking at around 260+ depending on guard bar.
it also opens up options for double overheads and fuzzy situations. 2H RC immediate j.P works as a fuzzy on anyone taller than bacon, and you can even do j.P, j.H, j.D into dust loop on pot.
fafnir doesn't work as oki, but it does work in mixup situations. j.S land fafnir, j.S whiff fafnir, post gb crossup into fafnir/brp, etc.
