I second Bill comments and want to add that if you have an alu snuffer ring that you don't have to strip the line. For some reason the alu rings don't lead to any wear on either the snuffer or spinnaker itself when leaving the mantle on. Been doing this with a plain spi cloth spi that was never lubricated for 3 years now and wear is absolutely minima. The snuffer itself show no signs of any wear. I do agree that glass or carbon rings are alot more sensitive to wear in this sense.
