  • Gnuvenson

    What is the ride like this vs the Riders choice?

  • Tarald

    what is the difference between eco-impossible and the space case?

  • GNU

    These two boards share a lot of similarities, but the Eco Impossible has some added features:
    Asym core 3, which is lighter and damper than the Space Case’s Asym Core 2
    Eco friendly and sparkly Bio Beans topsheet
    Extra light and Magnesium Fiberglass
    More pronounced heel edge Magne-Traction

    In short, both boards are PHENOMENAL, but the Eco Impossible has some added tech which will give it a lighter and even more lively feel.

  • Nick

    I am 5’8″ and about 250lbs. What would you recommend for a length.

  • Nick

    Also I have about a 10.5 to 11 size boot

  • Mason

    I would go with the 162

  • GNU

    Hi Nick,
    Sizing really varies depending on where you plan on riding the board at.
    If you’re going to spend most of your time on groomers and you want a playful/maneuverable board, go with the 156.
    But if you’re looking for something that will give you a lot of float in powder, go 162.

    The 160 is a nice middleground, so if you want something in between both of the boards I described above, the 160 will be kind of a quiver killer.

  • Richard Hoang

    I was wondering if you could mount the bindings set back and use it like a directional?

  • GNU

    Yes absolutely–that is why be build it with four different mounting options per foot.

  • Britt

    I’m a girl with size 10.5/11 feet looking for an all mountain/park board. 150 lbs. Which board would you recommend and what size? Assym or not? I’m digging this one but 156 is pretty big and I’m not sold on the asymmetry

  • GNU

    Not sold on asym? Have you ridden asym?
    You’ll most definitely be sold as soon as you ride it!!!

    If the 156 Impossible seems a little biger than what you’d like, check out the 153 Space Case. It’s got a very similar shape with similar specs! It doesn’t have the magnesium fibers that the Impossible has…but it’s a game changer and one of the most beloved boards in the line!

  • Reignman

    I’m looking for a board for my wife. We ride Baker. She’s 5’8″, about 150lbs and wears size 9 boots. She works out a ton and is very strong. She’s been riding a 154 BNice and a 155 Burton. She’s been riding for about 5-6 years. She hauls ass on groomers and is progressing quite well as I take her into more and more interesting off trail terrain. Looking for something more pow oriented to handle everything Baker has to offer.

  • Smurf

    Could you give me some advice on size please, I’m 215-220lb, 5ft 10, UK size 9 feet (?US size 10?), looking for a playful all rounder.

  • castt

    @GnuSnowboards:disqus I am a guy with 10.5 size, 170lb and 5.8 height. Will I be comfortable with 156 Impossible or should I look toward Space Case? Thanks!

  • Igor Nabhan


    Looking for a board to carve (really carve), hit natural features all over the mountain and do some low speed ground tricks.
    I weight 240lbs and wear size 11.5. I am a advanced rider.

    I’ve been riding the 161.5 Riders Choice for 5 years (normal width / last 3 models).
    I’m looking for a new board, and can’t decide between the Eco-Impossible 160 or the new Riders Choice 161.5.

    Could you help me? Thanks!


  • Really want this board.. Is it available in the UK?

  • Joe

    I have the same feet and weight, 5’8″ in height. First I though 156 is a bit long for me but bought it anyway because of its features. I must tell you, this board changed the way i ride. Im only riding for 2 yrs and already kicking some ass this season…some of them thought I’ve been riding my whole life. Speed demons in my group are having a hard time catching up. The sintered base on this board is amazing, it’s like having a nitro behind you…passing them all one by one. Assym and mag trak keeps my jumps, turns and carves super sharp and responsive and saved me from many hospital trips this season already compared to my other board that i bought new last season which when put in the same situation, would have been a total disaster.

  • Geoff

    whadup mt weird…
    I am looking for a all mountain board with a little more park focus, and I know the space case would be the obvious choice but I feel like it is a little played out… I am super interested in the eco-impossible, but worried about how it will handle on rails… Could you help me out???

  • GNU

    Check out the B-Pro or Ladies Choice–with a size 9 boot, there is no need to be riding a men’s board.
    Both of the above options are built with amazing materials that will excel in Baker’s thick snow and steep terrain, while still being fun to cruise the groomers at mach speeds!

  • GNU

    This board will definitely fit the bill!
    But for other ideas/options, check out our board finder:

    Or visit your local shop!

  • GNU

    Both boards will be killer for carving!
    The Riders Choice will feel a bit more aggressive and the Impossible will feel more forgiving!
    Because the Impossible also features some construction upgrades, you may also find that it does a better job of absorbing vibrations.

  • GNU

    You’ll want to contact your dealers to check!

  • GNU

    The Eco-Impossible is killer! It’s quite similar to the Space Case, due to the EC2 base contour, but also features some nice material upgrades.

  • Scott Lemon

    Hi, for the last 6 years I have been on the full rocker Travis rice (1 of the early models ) and the K2 ultra dream. I would like to know how you think the Eco impossible 2 would mesh with or replace those.

  • Scott G Hawkinson

    Hi Gnu,
    I’m looking at the 16/17 Lib/Gnu catalogs, and I’m kind of disappointed not to see the Eco-Impossible in them. I currently ride a 08/09 LibTech Skate Banana 159, but one of my edges is starting to pull out and I’m looking to replace it (with my broform, Stevens Pass employee). I use my skate banana in all conditions, and it is my primary pow board. I like the playfulness of my board, stability in high speed carves, good edge grip in all conditions and during landings, and the float in pow. I’m 5’10” 170lbs with a (tiny) size 7.5 boot. I was looking at the 160 Eco-Impossible or the 159 Attack Banana, I demo’ed the 155 Impossible Pickle a few years back and loved the Asym construction and Elliptical Camber, but I personally want something longer for riding Pow.

    How is the 16/17 Metal Gnuru 158 going to compare with the 15/16 Eco-Impossible 160? It looks like the 158 would be the best size from me, only 1cm under my skate banana.

    How does the 16/17 Metal Gnuru 158 compare to the 16/17 Attack Banana 159? The big difference looks like the Asym Construction on the Metal Gnuru, is there anything else?

    –Big Scotty Pimpin

  • GNU

    Hi Scotty,
    All in all, the 16/17 Metal Gnuru and 15/16 Impossible are quite similar! You won’t get the same premium materials on the Gnuru, but shape is going to be really similar! You should also check out the Lib Tech Attack Banana–it has EC2 also, and also basalt and a all of our finest materials–it won’t have asym, though!

  • Alexander Davila

    Hi gnu,
    I was wondering will by boot size 10.5 feet on a 156 impossible? Or would the 160 a better choice?

  • GNU

    You shouldn’t have trouble with either size.
    The difference in the waist width between those two sizes is just 2mm; so super minimal!

    Go with whatever size seems most fun to you!
