I would swap it for a Seimitsu LS-32 but getting the stick out of the casing is probably more trouble then it's worth, as I'd have to remove a lot of wood and try to put it all back together again.
I was wondering if I could replace the Sanwa cherry microswitches with Seimitsu leaf microswitches. I know Happ switches would work, but I'm after the feel of a Seimitsu.
I was also wondering, since the stick is installed with the shaft a little high, if I could replace the shaft with one from an LS-33. I'm assuming I'd just need to pick up an LS-33 shaft, spring, spacer, and e-clip, right? Is there anything else I'd need to make this work?
