quicklx: You have solid form from the looks of the pics. You suck your knees up by-the-book. Next step is to drop one of those arms and grab the board somewhere
I did have a couple grabs, but because our buddy with camera was to my right you can't see it in any of the other pics. I almost landed a 180 off that same roller, but my switch skills aren't quite there. landed on the tail and washed out. gonna keep working on it though.
