I am ready to order my control interface and have decided on the Mini-Pac from Ultimarc. I like that it comes with a wiring harness as I think that will make it very easy to hook up. My question is since I do not know what trackball I am going to go with yet, either the U-Trak or the Electric Ice-T. Should I order it without the Opti connectors on it? There is a price difference of $23 if I just order the one for the joysticks and switches. If I go with the U-Trak it would work with the Mini-Pac with the opti built in, I am not sure that the Electric Ice-T will. In either case I can order the USB connection for the tracball and not go through the Mini-Pac.
I was just curious as to any thought on this. What is considered the better option? Should I wait to order the Mini-Pac until I have decided on the trackball I am going with?
