Get a yak, they have a tankwell for when your diving, you can troll, there faster to get from point A to B, if your batteries die you don't have to kick for your life to get back, and you can rig the heck out of em', I have a caddis and since iv'e had "two kayaks now" i havn't used my tube in about 4 years.
you can get some really awsome deals on
http://www.kayak4fish.com heres a sample of mine wich is kind of basic but its good for me,just to give an idea if you havn't seen what they do to them these days.
"sorry no pics"all my pics are to big to post, i still have to figure out the whole pics on the post thing i guess, but anyway check out that site theres some good pics of rigged yaks.
