Yeah, in a narrow set of conditions hangls work really effing well. The rest of the time they are the pits.
Icy day with a moderate amount of chop and they work every bit as well as most other systems at low but not slow speeds.
the rest of the time they’re too heavy, don’t filter as much out as most other systems, too heavy, have too many parts to lose, are too heavy, put a lot of pressure on the points they mount to the board, are too heavy, are a nightmare to swap between board and, did I mention they’re too heavy?
The hangls in my experience work way way better on a slalom type board than any other type of board. I still have a hangl only Kessler I contemplated T-nutting it but could bear the idea of hurting the old girl. That board, is the finest piece of engineering I’ve ever been lucky enough to attach to my boots.
