Thanks for the tip Walt! I recently replaced the seals on my Profitec Pro 800 with cafelat seals - can't believe how easy they were to put on - so hoping it'll be the same in reverse when I remove them a year from now.

You should only have to relube the seals after a year of home use, not replace them.

About a month later and still no slipping after drilling. Made a youtube showing how it is. In the video I grinded finer than normal just to show that it doesn't slip regardless of grind size. Also can see the puck afterwards is perfectly smooth, i.e. no extreme channeling with piston aligned correctly. Wish now I had made one showing it before drilling, but honestly didn't think drilling holes by itself was going to do much, was just easy to do and so gave it a shot. It worked out pretty good. Thanks for idea Paul!
