Replying to Surface Blank park si

i decided im skiing on some surface blanks this season. ive heard a lot of mixed opinions about the ski and surface in general. Im a skier on a budget so the blank was first on my list of a cheap, and good ski. im not worried about performance. Im sure that the performance will be just fine. im more concerned on durability and the fact that i have never seen a pair of used last years blanks. im planning on getting at least a season and a half maybe 2 seasons if im lucky. I cant really say im the most hardcore skier, but i do beat my skis pretty bad trying new tricks and different rails. what do you guys think?
