I have used the Power Drive V2 for the past 15 years and loved it. The PD V2 with co-pilot, as Dutch mentioned, does require alot of attention because you are constantly having to steer it to stay on course. The Power Drive V2 with Auto Pilot is the way to go. For long line trolling, I liked the Auto Pilot just as well as the I-Pilot. I recently upgraded to a Terrova and really love it. It has the I-Pilot, but the only feature I use on it is Auto Pilot.
