I bought one yesterday. I'm not sure I'd quite call it a game changer, maybe just nod in the direction of more convenience, lighter weight and some added versatility. (out of a $80 product, that's not bad...)
So it is noticeably lighter than the stock Mystic Clickerbar 4.0 that my Majestic X came with. (FOR SALE btw...$40?
) I'm all for shedding some unnecessary weight on gear, as every bit helps when boosting and packing gear for trips.
The composite feels well built and the closure works well. I went with the traditional hook as I ride hooked in twin tip 90% of the time. The option to add a rope for surf/foil has some appeal for future use.
The wings aren't anything new, my Prolimit harnesses have had them 10+ years ago. They do work. It really keeps the bar from riding up and there is no need for a hold down strap. The newer bigger bar pad is super cush and comfortable. I'm stoked for this as once in awhile my bar would pinch my ribs.
Overall I think the Stealth is just going to make a great harness even better.
*Just a head's up:
There is no provision for a short leash on it like the Clicker bar. No biggie as I had an old ring/leash from another harness.
There is no internal safety knife pocket like on the Clicker bar pad. Again no big deal, I was due for a new/better safety knife. I just got Mystic's mini pouch/knife.
