Today, I had the nose up on the Tessy for a sec, then I tried to whip it into a 180 but only went 90 degrees. The nose came down hard and I left some of the Tesseract's cork bottom on the ground. I felt awful about it, but I have to say, that darn thing is a tough mofo!!! Didn't even leave a mark on the actual board!!! FYI~ that Tessy can take a beating!!!
