Hard to tell from the pictures, but looks like they may have a thicker shock cord than the older model? The older version had a lot of clay ballast making the nose cone quite heavy. On my first flight the 1/8" elastic snapped and the rocket came down horizontally less chute. Sustained cracks to the winglet glue joints.
These winglets apparently have a reputation for landing damage. Don't remember if it was the Rocketarium instructions or Madcow's, but it said there are two schools of thought: Tack on the winglets and deliberately have them pop off at landing, minimizing damage and repairs. Or, do the traditional strong glue bond. But if they get damaged, repairs will be more extensive.
