It's a really fun park ski, but they're insanely soft and ridiculously floppy when you actually go skiing.  Going fast through choppy powder on those totally works your legs and makes you afraid for your knees because it feels like the tips are going to come up and hit them.  They'd be a fun ski if I lost 50-60 lbs, unfortunately I'm a normal sized person so I hopelessly overpower those flop boards.
