I was hoping to hear that the silly MM was enough to avoid the need and gain a little more gasket surface on the liner, but what worked on The 87’s will work on the 89’s. I don’t expect to gain much as I expect they will be heavier than what I’ve been using, but they cost a bunch less. In time I’ll know.
