Just fiddling around with these mods tonight. I ordered the stiffer springs Sunday night from Divemaster, so we'll see how that goes.
I took the Cherry switches off a Super I had lying around and put it on my JLW, and it is quieter, but unfortunately it doesn't work with the 4 way restrictor. It's too easy to hit the corners on the Cherrys, as the acutuators are easier to move, so it makes the 4-way restrictor useless. I'll keep it mind if I do a 8-way JLW.
