One of the best setups I’ve ever had the privilege of using was a Sanwa JLW with a custom-made metal circle gate with LS-32 or 40 spring and a swappable bat top or ball top. Felt as close to a Wico360 as I could get without having one.
I can kinda relate to FPS problems. I’m used to bargain bin Microsoft 3-button mice with a regular scroll wheel and a rubber ball in it. The drag it had felt really nice and much more tactical feedback than this new laser/optical stuff. But hey, gotta change with theh times.
As usual, it’s all a matter of preference. They do have bat top adapters you can put on Japanese, but it really only feels right with a circle gate. I don’t ever believe there’s ever an actual mechanical advantage in using this stuff as long as it’s consistently functional. It’s all about what you’re comfortable with.
