New chaingrab?

ok guys this is what I got.

how I found:
OK so my friend plays as bowser. I tried the f-air chaingrab and it's hard to do since nana can't jump high enough all the time for the spike. So while playing I relized this and attempted. . . mid way through I though "bad iidea" and hit 'b' instead of 'a'. This caused nana to go into a squall hammer that carried the big green beast forward. after the popo's grab animation finished I dashed forward for the regrab. this only works 'till about 40% (around same % as the f-air chain before it smacks them to the ground.)

how to do:
grab -> throw down-> short hop -> squall hammer immediately -> press/hold forward 'till popo's grab animation finishs -> dash into a grab

issues?:
Is this common knowledge to other IC players? From what I tested the squall hammer is still spinning fast enough for the chain to work 'till about 40% (2 times) before the opponent can DI out. Does this work on all characters? I tested it out on most , but more effective on other characters like Bowser, king d3, DK, and R.O.B.

if this has already been tested and it doesn't chain like I think sorry for the post and I will delete.

Well Ima edit when I can test this but the Fair cg is ALLWAYS possible. Nana doesnt need 2 "Jump high enuf", if yur havin that problem wit it, try short hoppin ealier, the higher and later u jump the more time the oppenent haz 2 DI out of the combo. So its betta 2 jump faster than sooner..Even after the Fair lays em down, u can immediatly "Block Lock" makin the Fair Cg pretty consistent. AND when they get close 2 t3h edge u can short hop yur blocks 2 get 2 em b4 they go off, dthrow, shorthop, Fair Turn around thingy while DIing towards the edge and do the same exact thing back across the stage.. IDK if this iz a ifinite, prob not.. but.. lolz this is jus a theory really.. think dmg plays a BIG role in something like dis.. Ima look into it..

But anyway, Ima try yur Cg the soonest I can..

Haven't tried it, but there are several squall hammer CG's, so I wouldn't be surprised if this works.
