Isaiah and I both agree you are one of the best Iori players and have great setups and amazing reactions. Having said that, I have a general question about your neutral game and confirms.
Hahah thanks!
I noticed you most pressure with 2A, 2B and close C. How do you confirm and know when it will hit? Do you just have godlike reaction time or have a general feel for when the opponent will get hit. For example close C, f+A (x2) xx 214C. The special followup is unsafe, so when do you know to cancel into it? Do you just buffer 214.. then press C when you see the hit?
I just run in with d.B, d.A, and press forward getting ready for forward+A. If the d.B hits, then I press A and continue. For dash s.C, I just run in and see if the opponent is doing something and may get hit then I'll do forward A if I feel it's gonna hit.
Also, your hop ins. How do you decide whether to hop in with A,B,C or D? Like do you think about the spacing, how much blockstun you want to impose or how good the opponent's anti-airs are?
j.A - Up close fast air attack (air to air or ground)
j.B - far distance air to air, use like a poke
j.C - Up close slow but low hitting air attack - good against people who like to d.A anti air
j.D - far distance / air to air
j.CD - against people who use d.C and for super long block stun
If the opponent is good at defense, it seems you need to rely on either grab or crossup setups. Do you have specific setups you find most effective? For example I've seen you like to do hop A as a tick then go right into crossup b+B.
Yeah if they're able to block most of the things I do I'll go for grab/crossup/frame trap.
The best setup is using close stand B first then either
- stand C link
- stand C frame trap (slightly late s.C)
- command throw / regular throw
- another jump attack or cross up
- s.A, s.B then far s.D for poking
Cross ups are harder in console in that you can't hop over a standing opponent in console. So I use it a lot less now.
Finally, what are the most important combos/hit confirms an Iori player should know? Your go-to HD combo, what do you generally do when hit with a d+B/close C, etc.
Sorry if this is a lot of questions, I'll appreciate any response. 
Most important thing is to poke with s.B and s.D and j.B or D at it's max range to harass if you have trouble getting in. You have to really know his normals well. When you can get in, j.Cs and d.B, d.A pressure until you can hit confirm. Also manage your meter wisely meaning go for only combos using just super meter or just HD. Use both if it's for the kill. I tend to use only standard combos or HD combos. Standard combo would be s.C, f+A, qcb+C, super (or d.B, d.A as starter).
