I felt the same with my Evo but not catchy. Whenever I flat based I would whip side to side erratically. I think this is due to the razor sharp edges I don't know. I'll have to detune the tip, tail and slightly the contact point (not majorly, just slightly). I hear this allows for edge hold still but smoother transitions.
Catchy might be the wrong word. I did notice the edges are ridiculously sharp. The board actually cut my hand when carrying it. My gloves didnt fair to much better. Never had a board with edges this sharp before.
