Ok didh't know where to post that so here it comes :
I had a lot of fhanfus loop practice in training mode today and I noticed 4 variations in the FHNair to footstool "combo", depending of the spacing of said Nair. The variation resides in the kind of jump that I have to do after the Nair to footstool the opponent :
1-after a "foot Nair" (when falcon hits with his foot or his shin) I must dash a little before jumping,
2-after a "knee Nair" (when falcon hits with any part between his knee and his hip) it's a forward jump,
3-after a "butt Nair" (when falcon, facing away from his opponent, hits him/her with, well, his butt) it's a backward jump,
4-and after a "retreating butt Nair" then it's a backward dash followed by a jump.
Each of these follow ups work against CPUs (tested on ROB, samus and wario), but which one(s) is(are) legit on human players ?
