  • 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.
