Hey Zach,
I have CH pedals, Combat Stick, and Throttle....out of the three the pedals are the only thing that doesn't ever come out of calibration....and I have had them the longest.
The pedals do sit a bit close together so you will probably need to figure out what is best for you at first so that you can kill in comfort
I personally put my heels at the top of the pedals and depress down...I don't use the toe axis for anything just the Z axis.
All in all, pedals are awesome, they will definitely immerse you more into the game and probably will make your maneuvers a bit more precise.
