Okay, no one seems to have experience with the Happs Optical Rotary

How about the Midway 49-way joystick shaft compared to the other Happs joysticks like the Competition, Super, or Ultimate? Which one has the same thickness and roughly the same length?
I'm still trying to work the SlikStik SS handles into a new setup but I'm not having much luck.. Getting stuck with BLACK joystick handles won't look good with my colored buttons.
