Easiest/Hardest JF move to do for you?

I just remembered in Pungho's matches he's capable of doing EWGF after a d/f+2, never really knew it's a special one haha. And wow that's the first time I've seen Heihachi's OTGF, looks fancy!!

To expand on the answers regarding pEWGF (Perfect Electric Wind Godfist):

Don't worry about it 99% of the time. For most mortal players (of which I am no exception), it won't matter if your EWGFs are a perfect 13 frames (Kazuya) or 14 frames (the other Mishimas) or not. Even the pros typically utilize EWGF at 15 frames or higher, and it's still a better move than what other chars have at 15 frames.

The only two instances in which a pEWGF would actually be useful would be 1) for punishing 13/14f moves, but this is insanely hard to do reliably in actual matches since you'd have to have muscle memory and perfect execution that varies depending on every move you've just blocked. The timing to block and pEWGF after one opponent's -14f move could be entirely different against another character's -14f move, etc. Multiplied by every character and every 13/14f move in the game. Maybe practice against key moves that you see a lot in that range, but it's still damned difficult to pull off pEWGF punishment.

And 2) Kazuya's d/f+2 CH pEWGF. d/f+2 stuns on CH, and you have 13f to hit the opponent as if he or she were still standing (meaning you get free unscaled standing damage, and all your moves have standing properties). d/f+4<4 is 13f, and is real easy to spam after d/f+2 CH for decent damage. Or 1+2 (12f), which is another topic entirely in its possible (and fairly sweet) applications. If you're near a wall, you can b+1<2 for piss-easy access to a wall combo (or 1+2, with the benefit of the wall).

But the d/f+2 CH holy grail is pEWGF. Since pEWGF is 13f, you can launch the opponent into a full juggle starting from 50+ damage right off the bat. It's an incredibly powerful ability, and incredibly hard to perform reliably. 99% of players will never be able to count on this during a match, and they'd be much better off sticking with more reliable combos. Doesn't hurt to try and practice, but in all likelihood, unless you're incredibly serious about the game and have a ton of natural talent for performing the moves 100% accurately, it's not something you should worry too much about and/or feel bad if you can't perform. Then again, now that you can buffer a partner into the mix in TTT2 after the EWGF, even if you fail you can still come up with great damage off the knockback these days... I forget the specifics of how this is best done, seeing as my PS3 died right after TTT2's launch, but the advice is out there.

[Also, 3) pEWGF in combos. Unless you're making combo vids, stick to more reliable stuff. =p]
