After reading this thread, I've just modded my Hotrod SE : replaced the Happ supers by Sanwa JLW-UM-8.
They fit quite well but ideally I'll need to remove some wood so that the stick go higher on the other side of the panel.
After all good stuff I've read about Sanwa, I'm very disappointed with this stick (is it me or would the "JLW-UM-8" be *the* Sanwa stick to avoid ?).
First, the deadzone is far larger than on the supers. I've checked and it's due to the fact the microswitches are far less sensitive. Hopefully the UM-8 stick offers less overall resistance so it's not a big problem.
Second, I don't know why but for me the stick just feels *plains bad* compared the my Happ supers

And it's not a matter of subjectivity.
My UM-8 doesn't have a perfectly smooth motion from center to the sides, it's as if it needed lubrificant - what I cannot understand is why it would need some, as it is quite new...I'm waiting some time (so that the stick get a little used) before trying anything anyway.
Anybody else experienced the same, maybe ?
