For me the Pearl wingnut is the way to go. its a 5 second job, they look great, protect the cymbals againt keyholing and - for those who like that - is adjustable to allow some restriction of the cymbal movement.

At the moment I'm using gaffa tape to "secure" the washer, felt and sleeve. It's not very secure.
