wireless or electronic?

i converted the wife's bike to di2 this fall....she loves it. there were lots of situations where she avoided shifting her front chainring because the mechanical lever throw was too long and with her small hands she almost had to let go of the bar so shift to the big ring, so she'd just make do with whatever ring she started in. crazy, but a good use for electronic.

i also raced against some members of the US paralympic team once when i was in cat 3. one rider had one arm; di2 would have been perfect for him. (was cool to see his teammates help out at the FZ.)
