I have a GPWiz40 that I put into a converted X-Arcade 2player tankstick. Also sporting a pair of JLW's (which replaced some iL Competitions, that I felt were too tight after the JLF), which I have really grown to like, along with the JLF in my Hori. I soldered the grounds to one wire for the GPWiz and that seemed to work well. So, that said, once I get my 4 player control panel going, I'll probably retire my x-arcade and give the GPWiz a shot for rotary. Really excited. And I guess I'll go for the mechanical, since they are compatible with the GP-Wiz40. Any other rotaries besides Happs anyone would recommend, as I mentioned my issues before with the Competition style? I know the classic Ikari ones are around, but I want the stick itself to be more traditional, since it will have multiple uses.
