I have experimented w/ the reusable kind; I had hoped they would be easier to use, that I could just slide the old pads out and new ones in and not have to deal w/ adjusting, but it turns out that with old holders, it's just harder to get the old pads out and new ones in and I still need to completely readjust them anyway because the new pads are of course much thicker and generally a different shape than the old ones were by the time I pulled them out.
