Gnu Impossible Series EC2 BTX Asymetrical Side Cut $799
Intermediate to Expert All Mountain Freestyle
Hybrid Rocker (aka EC2) Assymetrical Twin Shape
 The Gnu Ipossible Series has a rather unique shape and was introduced in 2011.  It's called EC2 BTX and it lives somewhere between C2 BTX and BTX.  E stands for elliptical camber so instead of a V like bend down there is more of a C like bend down after the rocker. This provides a more loose ride but still allows your tail to grip the snow when in a carve. It's more loose and playful than C2 and C2 Power but still has much more of an all mountain feel to it than BTX.  The impossible lives somewhere between the Lib Tech Attack Banana and the Lib Tech Banana Magic in terms of it's ride.  The impossible takes an all mountain freestyle approach to the mountain that is very similar to the Attack Banana.  I.  This is similar enough to the Attack Banana in terms of sizing, flex, shape and riding style that its hard to recommend this expensive board over the Attack Banana.  There are some advantages though.  We feel the impossible series feels a little more stable between the feet and has a faster base. It also has a little more bite between the feet when it comes to edge hold.  If you can live with Mervin's (lib-tech and Gnu) mid level tech on the Attack Banana you might be almost or more happy because you can probably buy a good pair of bindings for the difference.  You can also save about $100 if you go with the Banana Magic and get a very similar but slightly more aggressive ride. Still this is a great board so if you are a drug dealer or a trust funder then have at it.
