The Cobra is a board that I helped design for that specific purpose after test riding the Heritage. I have extensive reviews on this site as well as my own site of both of them. The Cobra actually IS very similar to the Heritage in it's handling and the Cobra really does not chatter at high speed on hard grounded significantly more than the Heritage.
I grabbed a Cobra in large part off of your reviews and sold the Heritage. Loved the heritage but wanted something a little more playful and a little better in powder. Cobra/heritage were too similar to keep both.
