I have a Power Pole on my current boat which I just traded on a new boat. I opted for the Talon based on space and the lack of a hydraulic reservoir. I was at my dealer, Sonnys Marine, the other day and they were installing dual Talons on a FX 21 like the new boat I am getting. If you don not have a hydraulic jack plate the Talons bolt directly to the sides of the manual jack plate--the motor won't have to come off for installation; it will with the Power Pole. Overall the installation of the Talons is much cleaner--the only dislike I have for the Talon is the fixed position of the unit. When I had someone fishing the rear of my old boat I would partially deploy the Power Pole and it would be out of the way for casting; can't do that with the Talon. Most things are trade offs. This decision is like that. A few weeks ago I asked the same questions on the forum and some guys sent links to videos on the power pole. I can't remember the name of the thread, but it can't be more than three or four pages deep on this forum. The videos made me decide to go with a Power Pole again and then the other day when I was pulling the trigger on my trade I saw the Talon being installed.
Good luck with your choice. I don't think you can go wrong either way.
