What gear is my fin in?

[jasondbaker]

Sure, I think it is exciting that manufacturers continue to innovate.  I guess it remains to be seen if this is truly an innovation or just a marketing gimmick.  I would try them if given the opportunity. 

Here's a mini rant regarding fins.  Why do fin manufacturers continue to produce rubber fin straps? Or those ABS buckle systems?  I can't see any advantages, other than probably production cost, over spring straps.  And I've owned both types of straps for years.  Maybe the margins are really good on replacement rubber fin straps.  This is an area where it would be trivial for fin manufacturers to innovate.
