I am delighted with its beautiful, efficient design. As a Mechanical Engineer, I appreciate the top quality materials and durable components. I have enjoyed using both the All Mountain Master and the Powder/Mogul Master, which have tremendously improved my balance, coordination, and endurance...My skiing has undergone an amazing improvement since I started using the System 4!...It is easy and fun to use, and I would recommend it to anyone who wants to see a quantum leap in their ski technique in the shortest possible time!
