I just got a new float tube for my birthday and my wife was smart enough NOT to get the package that included a set of fins.  My fly fishing club buddies are not fans of those fins, saying the Force Fins are the best choice.  Now, I'm trying to see if anyone has a set they're not using or could direct me to a good deal somewhere.  Ebay does NOT have the float tubing force fins available at this time, I already checked.  These are not regular diving force fins, but a particular model with a boot entrance that allows stocking foot as well as felt bottomed boots.  It's adjustable.  Anyways, thanks.
