Hi Mike, Finke has upgraded to a space age material that has solved the problems of the old plastic rotors. The old rotors can be replaced with the new. I am sending a horn to Finke to have the old leaky rotors replaced with the new material and, if they are anything like the new horns I've played, they should be fast and tight.
BTW, I oil all rotors, plastic or not, to help prevent the build up of grunt/crud. Of course, the best prevention is, as mentioned many times on the list by Prof. Pizka, good hygiene, abstention from the refreshments/cookies at intermission and dumping water before the horn is put in the case. Regards, Jerry in Kansas City _______________________________________________ post: [EMAIL PROTECTED] set your options at http://music.memphis.edu/mailman/options/horn/archive%40jab.org
