I've owned 4 different float tubes and I'm on my 2nd (last) pontoon. Float tubes are fine and have their time and place, but for the sport of bass fishing, a pontoon all the way!

I have to agree with John. The pontoon is faster, more stable, and it can hold more gear. If you are trout fishing or only plan on using your craft once a month or less, then buy a tube. But if you are bass fishing and you go out every weekend, then you should strongly consider a pontoon.
