So has anybody been able to use the airball protector with their LE/premium? Shots to the ramp will hit the protector, and backhands are impossible with it in place. I tried to shim it up with a couple of washers, but you can't screw the nut back down when you do.
Also, I finally replaced the left ramp switch, because the one on there isn't any good. It's an Omron switch, which is more stiff than a Cherry switch, so I found that once in a while it won't register. I swapped it out with a Cherry and it's perfect now. The pic with the three switches shows two Cherry switches (top, right), and the original Omron that Stern used (bottom/left). The bottom pic shows the new switch in place. Even the slowest rollers register just fine.
