@ket,
I also use the [now discontinued] RE slider bar. There are two versions: one with simple holes thru the bar and one with pressed-in grommets. The latter is prone to wearing [and corrosion] thru the grommets, which causes a sharp edge where the line passes thru the bar. Since most of the line wear is at these pass-through holes, I replace the line way before sliding of the bar causes any wear. The grommets were an 'upgrade' to make a more radiused hole, which unfortunately caused a new problem. The solution is to remove the grommets [like in the version of bar in your link below]. Try to do so without creating another sharp edge. After removing the grommets, I polish the edges of the holes with a Dremel tool and a polishing burr and/or lightly sand/file.
I hoarded about four of these bars, because the design is simple. I might try enlarging the holes to run the next size thicker line, which would increase the line's life.

Edit: Adding... Over the line, I use the DaKine slider [having a conventional chicken loop hook], a stainless steel shackle and machined pulley and I'm about ready to try just a couple of simple stainless rings.

Little over a year ago I rigged up a pulley on my rope slider.

Zero wear on the rope so far. I don't think I'll ever have to replace it.
