I did a dual cable version of these on a hopped up bass boat years ago and loved it.  No feedback does take a little more effort to turn the wheel, but not much.  With this setup you can literally take your hands off the wheel, hit a wave, and the boat will go in whatever direction you left the steering at.  As a side benefit if you do get thrown out, and for some reason the kill lanyard failed, well, at least the boat isn't going to circle around and come after you :)
