One of the problems with the TE stick is that it has the Square gate. I got my own TE stick just recently, but it died almost immediately, so I’m in the process of getting it replaced. sigh But I really like it so far.
One of the things to learn about square gates is that you can’t use it like you do all arcade sticks you are used to. In the U.S., most arcade sticks have a circular base, so what we’ve all ended up getting used to is “grinding” the stick against the circular base… using the circular base as a crutch to help us perform the QCF and QCB motions.
What you learn about these sticks, though, is that they are designed for FAST input. The reason TE sticks are so good is because they require VERY minimal motion for them to register. So one of the reason Japanese players can pull things off so fast is that they’ve never used the base as a “crutch” to guide the stick. Actually, what they do is they are almost “floating” the stick and moving it themselves. In other words, they rarely touch the stick to the edges when doing QCF motions and QCB motions. Instead, they take the stick and slightly nudge it down and quickly rotate it to back.
The reason you are having trouble doing the QCB motions is probably because the stick gets “stuck” in the corners because of the square gate. The way to counter that is to not use the edges to move the stick, but to rely only on your hands and wrist to move it yourself in that motion. Not only will you find out that it works well, but it also allows you to do motions a LOT faster.
Also, it helps me a but with QC 2 in 1’s. Whatever you plan on doing, you can rest the joystick comfortably in the opposite corner. So if you plan on doing a Fierce into QCF + Punch, hold the stick in the corner of D/B. Then, when you hit Fierce, just move the stick to forward while subtlely passing through down and down/forward, but don’t try to use the edges of the base to guide the joystick.
It will still take a TON of practice to do this properly, no question. And if this all fails, it’s pretty simple to get a Octagonal gate and swap it out of the TE stick.
You’ll have to void your warranty, but it might be worth it.
P.S. As for Chun’s Head stomp, yeah, that can be a pain in the ass. That just requires practice. What you do learn about top players is that they are very careful with the joystick. Motions are actually better off being very subtle as opposed to very defined. Try that out for a while, and see how it works for you.
