Ah, then I can’t guarantee whether it’ll work or not. Whether or not Sanwa and Seimitsu are swappable depends entirely on what kind of mount you have in the Qanba. While universal is becoming fairly standard, I’ve got no personal experience with this stick.
I greatly prefer the LS-32. Shorter throw, slightly less pronounced dead spot in the neutral, the levers have a nice “bounce” to them to let you feel engagement before it clicks. It’s the stick of choice for many old school Capcom heads and people who are into shmups. So far I’m enjoying it more than the JLF.
While the JLF is popular, general consensus is that it’s sort of the “all-arounder” stick that does nothing well and nothing bad. But the build quality is nice as well on both sticks.
A worn out Sanwa JLF will feel better than a worn out LS-32 imo, but in either case, a general cleaning + relubing will get things feeling new. For me, Seimitsu LS-32 has so far been my favorite (and the most popular Seimitsu stick) and Sanwa JLW is my favorite Sanwa stick.
