I would recommend the two person Big Mable tube. You can tow it two different ways. If you tow it sitting down, it's not too crazy, but if you tow it from the other side and sit on your knees, you can get a pretty wild ride and some serious air. If you Google "Gladiator Big Brawler," you'll see an essentially identical tube that is MUCH cheaper. You can get it for around $110 shipped right now from the first listing that comes up if you use the 30% off coupon they have on their front page. I can't post the website because it's a competitor.
