I have a 2010 GNU and my wife has been riding GNU boards for 10 years. They are good boards- quality wise they are really no different than Lib-Tech. The AG is a sweet board but it only has btx (as opposed to C2). I found it to be softer than the Rider's Choice and I probably would have got the AG if it came in a smaller size than 155. I don't know how it will fair in the park. IMHO, you might want to take a look at GNUs and Lib-Techs with the C2BTX like the T.Rice or Danny Kass.
