I would go with a cable.
That being said, when I fished with Braink last year, I was pretty impressed with his electric. That was on the Croix, in pretty calm water, steady trolling along a break.
Down here, the flow seems to be much more significant, and it’s nothing for the boat to turn a 180 if I’m fighting a fish or slipping a wingdam. In those situations, I want the instant response of the cable. Also when I’m in shallow water around rocks and trees, the cable seems like it would be more rugged. Like someone else said, being able to steer without looking based on where your foot lies is also nice.
There are situations where the electric would be nice, but I can’t think of any that couldn’t be done with the cable steering… without any real experience I’m basing it on gut feel, but I can’t believe the opposite is true.
