What J says:
"The Metal has all of the high performance, powerful benefits you'd expect from a ski with Titanal metal in it, yet without the extra weight. The secret to it's award winning design is in the way we've optimized the metal laminate's geometry & location to add power only where you need it, and reduce weight where you don't. The result is exponential power & stability with a shockingly nimble, lively & fun feel. You've got a ridiculously fun cliff stomping, crud crushing, pow surfing ski that will also have you smiling ear to ear on groomer days laying down high-speed hip dragging carves like you just won a gold medal in Olympic GS. #JMetalSki"
What I thought:
I got the Metals from J last spring, and skied them about 10 days here in the PNW. It didn't take long to get used to them at all on my first day, a sunny, slushy day at Crystal Mountain. The dimensions are nothing crazy, neither is the ski really, but that's kind of why it's awesome. They do a really good job of balancing ease of skiing and stability. This balance means you don't need to think too much about the way you're skiing, which is cool, you can just go rip.
They do have a 'top speed', and even though they have a metal laminate, as suggested by the name, they can feel a bit light charging hard on choppy snow. Though I may have noticed this more as I was coming off of 191 ON3P Billygoats, which are long and stable.
The hard snow, and groomer performance was pretty fun. I ripped a couple laps on Palmer while at West Coast Sessions, and found that you can drive them well on groomers. I can't comment on durability, as I only got about 5 or 10 days on them, but the construction gave me no reason to worry.
Who they would be good for:
The Metal was fun, and easy to ski. I think It would be a great ski as an (almost)everyday inbounds alpine setup. The metal helps dampen the ski, so it can handle tracked snow easily, and the rocker makes them fairly quick to throw around. I'd imagine they'd surf and slash well in pow, and that the 106mm under foot would be plenty wide for most days. I'm not much of a jibber, and I'd say they lean more towards a traditional skier like myself, I don't see issues with popping around and launching airs though. They can still charge, and pop, but it's a ski your dad would love as well, because of the mix of stability and nimbleness. Plus, if you get your Dad on J Skis, he'll be the coolest Dad around.
