I have cable shifters for my dual case setup. I found it was a pain for cable routing, bend radius and all, 3 cables, imagine 5. Just saying. I have pics in a thread on here. Air would be sweet, but then you have to add a bunch of control solenoids and an air supply to get it to do what you want. I like the cable idea because you still have the feel and a direct connection to the cases. No wondering if its shifting. Local kid has that setup on his 4Runner, well he actually just sold it. Carry on, I'm enjoying this build up.
