Lizard skin or dynamat or hushmat?

Can't give personal experience feedback but I'm the same boat. After spending a lot of time removing undercoat I decided against a product like Lizard Skin or bed liner because of cost, potential mess, and diffculty in removal if necessary later. For sheet type I'm leaning towards RAAMat for cost and performance.
