The uhpe strips work good. Used and still use paste wax on my cast iron tables. For my cabinet saw, when I built the last fence and guides, I made sure I had a rear rail that I had a guide float on, so both sides of the fence was supported. The problems I had before was guides dropping into the miter slots as they went over them.
My panel saw does not have miter slots... and has an adjustable roller under the rip fence, so that the roller rolls over the table. That fence (with the cast iron "L" frame) is well over 30 pounds, but slides like silk over the table. I thought about adding a roller in a bracket to my cabinet saw's rip fence. But with that new panel saw, I really don't use the Rockwell any more.
