TheChad_87, that combo I listed - corner f41, b2af, fan, ff~b2af, ff~333~cutter, 333~cutter does 53% in version 1.05. 55% off a jump punch. It is considerably more difficult than your version of course. In a tournament, I would use your version because whiffing a 333 in a combo like that means you eat a wakeup.
Also, in a tournament, I would use jk~fan, ff~4~fan, ff~2~fan, ff~2~cutter for 39% for the piece of mind of not missing the f2 or the last hit of cutter.
NOTE: If you land a JK~Air Fan on a crouching character or one using a low attack like Mileena's d4, you cannot get 4~Fan, 2~Fan. You have to settle for a smaller combo like JK~Air Fan, ff~4~Fan, ff~4~Cutter for 36%. Not a big loss, but something to watch for when you land a JK.
Ernovaku, I use that combo a lot as well when I need it. I would recommend not using meter to extend an unbreakable combo unless you absolutely need it. That combo (aaFan, iAF, Fan, iAF) does 24% unbreakable without using meter.
Another unbreakable combo I use is f2~EX Fan, ff~Fan Lift, Fan, iAF, Fan, iAF for 29% that you can extend by doing 2~fan, ff~2~cutter instead of the last iAF. You would be ending with more damage (34%) at the end which is breakable but if they break it they lose life AND meter.
