I thank ALL of you for your input. I am pretty set on the SF with perhaps a wheel, and pumps, both K pump and electric, although I seem to have a lot of hot air my self. At my age, I doubt that I will be doing much hiking into remote lakes and river launches. I presume that with the SF I will have to find a way to rig my Minn Kota and battery. Give me something to do with all my spare time. Thanks again to you all.
