Quick write up from my site.
03.07.29 Well, received the stainless steel joysticks above after a week delay, have been using them for a couple of weeks know. They look beautiful but they're so heavy, they impact game play negatively. The only game they did really well in was Robotron [not in itself a bad thing of course], but even for simple games like Pac-Man and Donkey Kong releasing the stick from a right push would cause the pendulum effect and it would end up hitting the opposite micro switch on the swing back to the left and have Mario facing in the opposite direction. Fighting games felt sloppy too. It's too bad, I really wanted to make them work. They dropped into my Happ Supers but the default springs just aren't built to handle the weight of these things. So I ended up putting the Supers back in. I did like their cool to the touch and smooth feeling. It would be nifty to perhaps hollow them out and get at least closer to the originals weighting.
