I'm looking to purchase a float tube. Being new to the sport, I'm not sure where to look or what features I need. I'm 6'2" and weigh 230lbs. so I'm thinking I need the heavy duty model. I want a good tube that will last a long time and I'm ok with spending more for a quality tube. Any suggestions on brands and models would be appreciated. If you reply, please let me know where you got it. I was plannning on putting this purchase off for awhile but with the rivers this high I think I'll be on the lakes for now. Thanks for the help.
