I had the evil twin but sold it because I thought it was way too stiff for that type board.
Keep in mind that mine was the 2010 model, just before bataleon changed to the new factory. Their boards used to be built much more sturdy and had much less flex throughout the line. Not saying the new boards are bad in any way...they're just no longer "over-built".
I've since bought the GW and, although I haven't ridden it yet, it "shop-flexes" a hell of a lot more than my ET did. The GW has similar features to the ET, including a sintered base, but has the added plus of carbon.
