Ive got twin 8ft blades and 36volt ultrex on the fx20. Ive gotta say with all the varying lakes in this region, both are still awesome to have depending on what lake you head out too. I couldn't imagine not having either anymore after having them. I prefer the poles for 8ft and less / boat ramps / fishing in flats (the boat doesn't swing into the wind) and the ultrex for any reason you need the boat to hold a position. I love being able to fish slower in the wind on main lake structure. Also re-tying or eating a snack is so much better now. the power steering is sweet in that the motor always stays pointed in whatever direction you left it and being able to instantly change the direction 180* with no pressure is nice around boat docks or getting a lure unhung off a stump or something. IMO the ultrex is worth more than the price its sold for.
