[quote name='Antipodes']Keep in mind, I've only owned the stick for a week so take this for what it's worth.
The stick's shaft is supposed to be rotatable, which, by extension, will make the ball-top rotatable. If the ball-top feels too loose, you can try unscrewing the top, then tightening the bottom screw of the joystick.
When I opened mine, the screw was already tight but I tried to tighten it a bit more. I wasn't able to twist the screw noticeably, but it did seem to help ever-so-slightly. It's possible that there was never any issue with my joystick, and that it is very likely that there is none with yours.
Surprisingly, the hardest thing for me to get comfortable with was the short length of the stick and the rotatable ball-top. I thought I would have a problem with the square-gate, but that turned out to be a non-issue. The stick would be perfect if it were a bit longer and the ball-top was a matte surface for extra grip. I think the problem is exacerbated for me because I wash my hands often and need to apply lotion (oil) to keep them from drying out.
Opening the joystick form the top might technically void your warranty, but I'm not sure they will be that strict for something this simple (you don't need to break the warranty sticker). That said, you should contact Madcatz if you want to be sure.[/QUOTE]
Just pick up a Sanwa Bat top for your TE. They are longer, bat toppier, and matte finish
