I almost stopped using any JLF sticks altogether until ordering Toodles round restrictor gate product ( Godlikecontrols.com ) . Holy whoa…!! That thing is freaking AMAZING!!! I am waaaaayyyy impressed at what it did for the JLF!! Which is really great because those things are easy to find.
I also think that the LS-55 Spring is excellent in a JLF.
Hmmm…for some ideas…If you want a super sensitive non- HAPP STYLE arcade stick…
A Seimitsu LS-40 has a ridiculously short throw that I really really like.
A Seimitsu LS-32 has a medium throw that also really shines with a circular gate.
While using an LS-40 or an LS-32 I prefer a JLW spring for appropriate tension.
My only gripe with the LS-40 is that there is no true stock circular gate. So a bit of plastic shaving is required on the white plastic mounting piece to make real use of the included Yellow gate.
Oddly enough there is a really inexpensive Zippy brand arcade stick sold for about 10.00 from ParadiseArcadeShop.com that has levered microswitches, will take a LS-32 round gate, a JLW spring, and the throw is actually almost as short as the LS-40! It’s about the same overall size as a LS-32 even. Pretty schweet for a ten spot.
The new Seimitsu LS-58 has some super cool looks and is supposed to be a medium throw style of stick but I have not ordered any yet so can’t say from experience on that one.
So anyway I also recommend checking out Slagcoin.com. That is a wicked good source of information!
Plus it’s pretty fun to just try out different arcade parts from time to time and just sort of see what best suits your style of play.
Have fun man!
