Ah ok. I was just wondering because you said it hurts/cramps your hand hitting P+K. So I thought maybe you had a funky layout, hahah. But that's a pretty natural one for your hand. Maybe it's just one of those days is why it's hurting.
Using my thumb for G felt too weird for me, and I figured I'm most likely never going to Japan, so I just used the ol' Street Fighter type layout since I was already used to having my fingers on the buttons like that.
By all means, its all about customizing and finding what works for you! I think my problem with the cramps is that I tap P+K -> K and P+K -> P really fast and I'm not used to doing that for hours on end! It's better tonight now that I'm not struggling so much with the timing.
I also found a trick to landing P6P -> Chifu and P+K -> Chifu more consistently. In both cases the you cannot rapid fire the P+K into P or K, but if you P+K and double tap the next input, P or K, it comes out and you have enough time to set up for K -> P+K Tenfu.
P+K -> Chifu is gold! P+K has great range and works great off of SS P (sitdown) and after 3K (+16 post-stun), on it's own P+K has so much pushback most follow-ups wont reach but Chifu puts you right back in!
@Chapstick, I will check it out. Edit: it's just like Malfury said, if you do 7K -> Chifu K you're gonna get either a 3 hit combo (both hits of Chifu K hit) or 2 hit combo (only the 2nd hit of Chifu hits). It all depends on the timing of P+K to activate Chifu.
