Hey Tom,
Nice work on your multiwilliams project, looks great!! Have you had a chance to compare those Chinese Wico-clones to real Wico joysticks? Compared to a real Joust, I figure no other joystick would have the same feel as the original's with the spring steel tensioners, but are they that much worse for Joust than real Wico's? There's really no choice but to use 8-way Wico's on a m-w cabinet for Robotron, Bubbles, and Splat, but I would have hoped that the Chinese sticks would be close enough to not cause any problems.
Again, great job on your cabinet!
