On the 4iiiiiii pods, my guess is the epoxy is stronger than the pod so taking it off means obliterating the pod.
As DC Rainmaker wrote in his "first look" writeup on the 4iiiiiiiiiiiii unit, (paraphrasing) regardless of the merits of this particular unit, it's an interesting time to be in the power meter market.
On another topic. I am going to install aero road bars with internal routing. How annoying is it to pull and reinstall the electronic wires on 7970* shifters? Do I need the plastic tool or can I kludge it?
*for ygduf: 7970 is a shimano model number for first generation electronic 10-speed dura-ace, production run September 2011, Kyoto prefecture, late afternoon shift, shop floor manager Toshiro Mifune Jr. They had pickled eel for lunch that day in the cafeteria.
