Big 'Ol boy here and am considering getting either a float tube or an inflatable kayak for some of the streams and smaller lakes to fish from. I'm about 6' 4" and weigh 310 and am a little unsure as to what would be the best choice between either a float tube or an inflatable kayak for these purposes.

Any guys out there with similar size that has any experience using either one of these items I would greatly appreciate their input.
