I had Pipe Cleaners this season and they were by far the best ski I have ever owned. Perfect flex pattern for skiing park and also hitting up some groomers, trees, and light pow. They have the same 2.5mm edges as the AR6s so they are solid on rails/boxes. If you maintain the base by waxing them every 2 or 3 or 4 times you use them not only will they be much faster than almost every other park ski on the market, but the bases will be very durable against rocks, rails, boxes, stumps, logs, roots, etc.
