Hi Jennifer, If you use a Dynalite spinnaker with a Dynalite snuffer, you have the slippery cloth sliding across slippery cloth and the best possible snuffing action. It works very well on our Mystere 4.3 - I recommend getting the 1.5 ounce cloth for the snuffer. That also works well for our small 4.3 spinnakers - flying well in as little as 3 mph "wind". I am not sure how well it would fly in light air with a larger size spinnaker but it sure is much more durable for snuffing than the .75 oz cloth. Snuffing is great but it is relatively abusive to the sail so durability is a good thing. Hope this helps.
