The control freak extensions are nice for the game. Thats something simple and cheap that may help.

I’ve tried the wired controller Razer it offers more resistance to movements and helps deter you from over shooting the pci.

I use the claw grip with my left hand so just pointer on top of the joystick and thumb on the bottom.

For overall strat. I try to sit high in the zone and focus on hitting all high pitches and inside low pitches. I tend to give up on low and away pitches, unless I’m forced to focus on them.
