One method to fix the initialization issue would be to use pots for feedback instead of encoders. OR we could continuously read the current position and use that for initializing the position upon instantiation (it defaults to 0).

A quick note about that:
There's currently a bug with the Jaguar firmware. The first time the "position enable" is called after the Jaguar powers up, it sets the position to 0, regardless of what you wire in.
So, if you're doing this, make sure to call "enable" twice, and just wire the value to the second one.
If you're using Black Jaguars, they will function down to 5.5v, but they need 7v to start up. The Tan Jaguars can function as low as 6v.
For your uses, however, it does sound like a potentiometer would work best.
