@Dime I would try to jump forward and j.MP, or do j.MK fly j.3MK > ground confirm. But due to the height it launches + H Fiber doesn't provide much hitstun (Updo / Pillar / LBE allows you ample time with OTG in comparison) i was finding it a little trickier, that's all.
The issue I was having is that by the time I see that H Fiber has connected, the process of j.MP for the confirm takes too long (j.MP has slow start-up) and the combo would drop. I'm going to try setting the dummy to random block and attempt to confirm with some of these super jump j.MP strings. I was normal jumping before, so this could make all the difference. Thanks for the input everyone!
The confirm isn't something you have to be 100% on. I see taluda bite and do the superjump jmp even when fiber is blocked on occasion... Not that much... But it does happen. What you are doing is trying to go for 100% confirmation... Try to tone it back to like 75% confirmation if that makes any kind of sense... I'm just saying you should have a slightly itchy trigger finger on the jmp, imho.
Also, fuck it, I'll tell you what I believe as far as the other assists go, many disagree with me, but besides one Chicago painwheel, I haven't seen any pw convert updo or pillar nearly as much as I (or any pw for that matter) can convert from BE L... The reasons for this are:
Converting updo and pillar in training mode is fine and easy. Call the assist then dash just as or right before the assist comes out and the conversion is easy. But in a real game you won't be able to do that easily without putting yourself into harms way. And you may come to find that if you try to react to the assist hitting that sometimes... A lot of times actually, your dash will be to slow and you won't hit the otg... But tbqh that's the GOOD news.
The BAD news is that pw basically CANT convert in a real world way when she's made to block heavy attacks just as the assist hits the opponent... Think of an enemy pw dashing in and making you block her st.hp, but you call your assist just as the st.hp touches you... The enemy painwheel goes for a ride... And your like "yes" and you dash forward to get the conversion... But painwheel doesn't move.... Yep, that's right, your still stuck in blockstun and have to wait for that blockstun to be over before you can even start your dash. By the time you recover from your blockstun and get a dash out, the opponent has already recovered. This actually happens a fair bit. I'd say at least 30-50% of my ground assist hits put me in this situation... Which means that I was losing that much damage everytime I didn't convert the assist. That actually is very important as you can imagine.
And finally, when using updo or pillar or h chair for beo or fiber for fortune... You will find that it is nigh impossible to convert these assists if you are jumping backwards and calling the assist. The assist will hit, and you will land, but by the time you get the dash out, the fact that you are so far away plus had to land, plus have a slow startup dash plus a slow pickup move in cr.lk... Theses factors all combine to make it near impossible to convert an assist hit while jumping backwards. Sure, you can fly and convert as some have said in the past... But it's more theory fighter or a rote guess that the assist will hit. If your assist gets blocked and you fly directly above your opponent. Trying to react to the hit... It isn't a good look. But feel free to try.
Finally, BE L basically covers ALL these weaknesses. And still allows for super easy otg confirms. So you can confirm from the ground or any air assist call. And no amount of blockstun will be enough to keep pw from being able to dash into an otg conversion.
It's for these reasons why I feel like BE is a great assist for pw. I can guarantee that my assist hit to conversion ratio will be better than any updo or pillar user, and more flexible than a fiber upper user.
The only way for someone to have as good a conversion ratio for pillar or updo is to autopilot a midair confirm which will leave them totally open to my own counter assist call and get them happy birthdayed for their trouble.
But don't take this to mean that pillar and updo are useless, they are far from it. They just won't have nearly as high a confirm safety and conversion ratio as BE L gives. They are still great gtfo moves and you will still be able to otg convert many of the hits that you get.
So anywho, just practice autopiloting the fiber upper conversion against the training mode dummy and against the computer till you notice that you can react without autopiloting.
Fiber upper is still a great assist for pw, as are pillar and updo, because you don't have the liability of BBs bad matchups nor his weakness of getting overheaded for free :)

Oh yeah to make it very clear since I only eluded to it before, I think you should try out all the dp assists in real matches against human opponents to get a feel for what you like best... You may have different insights to what I have, it's best to try to experiment a bit before you go all in with a full team to try to main. You want to be as happy with your eventual team as possible.
