The only concern I have about the Ultrex is the missing break away spring mechanism. I understand that the design of the power steering keeps Minn Kota from using that system on the newer motors. In our world, down here in Louisiana, you are going to encounter large stumps and wood obstruction in places where you migh not expect it. I haven't seen anything negataive, but I'm left wonder how the rigid shaft will really hold up in a direct hit on a solid stump. THe composit shaft is flexible, to some extent, but they are not unbreakable. This issue won't keep me from getting one but I remain curious about a direct hit on something that won't move a little?
