This seatpost reminds me of my badminton racket, in that the carbon fibres seem to be unidirectional along its length. In a racket this gives a flexier shaft, and it should mean that the post has more lateral flex than if a standard cross weave was used.
Since the post is at an angle, and part of your mass is exacting a lateral force, you should get a slightly increased dampening effect. I can't claim that I really noticed the difference, but it might save you a few saddle sores over a long day, especially if you run a long post. The clamp is a standard alloy affair and though it's nothing special it works well. At 225g for a 350mm post it's light, but not super light. Maybe one for the tall Audax rider...
