They are great skis, very similar to the Armada Ar7 execept thay have race base and they are slightly lighter and softer in flex. The race base is a higher quality base than the S7 base on the Ar7 but you need to wax it more frequently, otherwise is becomes less durable than the S7 base. The benefit of this however, it that when the race base is freshly waxed it becomes faster and more durable than the S7 base. They have the exact same edges (2.5) as the rest of the Armada park skis so durablility shouldn't be an issue on the rails.
