For fist of fury to work, do 1,1 then quickly slide your thumb back and forth between 2 and 1 for the follow up 212. Off of a jump in punch, you should be able to hit confirm 1,1 on its own anyway (with practice I'm sure you'll get it down), but it's very difficult to hit confirm a raw 1,1, that's for sure. As far as ending block strings with hats, never end a block string with straight hat. When you want to use hats in a block string, go for low hat or occasionally, ex low hat. Low hats are only -6 on block which makes them for the most part, safe, with only a few characters being able to punish (and the player has to be really on point to punish them). Ex low hat is +5 on block so you get to continue pressure. Use low hats off of f23, f21, b321 (probably Lao's best string).
