I also think the Motion has a nicer ride. The Spectre was a much harder ride in bumpy water. The Spectre also sounds much louder when it hits. The echo inside the hull is very loud. It sounds like your hitting concrete when you re-enter the water. The Spectre also Porpoise's between 70 and 85. Most Spectres need a tunnel tab. The Motion NEVER porpoises and I think it's a much smoother ride. Like I said, i owned both.
