Thanks Jay!
This is exactly what I needed to know. I'm relieved that I'm wrong, and now I can scrap half of our Spikes if needed. I wonder how many teams there are who have too many Spikes controlling solenoids because they aren't aware that FWD/M+ and REV/M- can be controlled completely independantly of each other. That both can be "turned on" to +12V simultaneously (and the LED on the Spike turns off to let you know what's going on).

Yes, you can control the M+ and M- completely independently of each other! Like I said in my previous post, it's best not to think of the pins as FWD and REV, just 2 different data pins that control 2 different relays (conveniently packaged on the same spike).
The only problem I can see is if you blow a fuse (either on the spike or on the fuse panel) then you lose control of 2 solenoids. The only way that would happen with a solenoid is if you accidentally shorted the wires together though.
Once again, I recommend reading the manual. They tell you exactly how to do this in there.
