I am planning my 2 player control panel and I am leaning towards ball top U360's (hard spring, circular restrictor) as my main joysticks for each player. It seems to be the most versatile option for emulation. I am also thinking about having a 2nd joystick for each player so we can play Robotron, Karate Champ, etc. Good idea? If I do it, I don't think it makes sense to spend the $ on U360's for the 2nd joystick. My question is what do you guys think would be a good reasonable option to pair with the 360. Something that is somewhat similar in look and feel would be ideal.
