you wouldn't take a Porche 911 turbo to go rock cralling in Moab, and you wouldn't take a lifted rock crawler Jeep to race in La Mons.

John, I've talked to a couple of people about dual Kollmorgens but I would personally just go with higher and higher voltages until I was happy with the power. 2 Kollmorgens both with external controllers would start to get expensive. I will say though, Kollmorgens do have a nice amount of torque and 2 would really be a kick.
Matt, good to hear that you can drive 2 controllers off of one servo tester. In that case I'll probably go with another cheap hall throttle with a voltage regulator to power it.
