I did a little NON-scientific yet practical test just now. The test items: 65lb Stren Super Braid yellow 20lb Spiderwire Super Mono 20lb clear/blue 50lb Silver Thread AN40 (old but kept in cool storage) All fresh off the factory spool. 65lb Stren SB is about the same diameter as 17lb mono so I figured that it'd be a good representative to use the 20lb mono against it. The Silver Thread 50lb line is thin for 50lb mono, but still much thicker than the other two lines. I cut an 18" length of each line. I then took each length of line and rubbed it directly across the sharp steel toothed edge of my shop vise in the garage, and counted how many passes it took to abrade through the line and cause it to break. Spiderwire Super Mono 20lb test took 39 passes break. Silver Thread AN40 50lb line took 79 passes to break. 65lb Stren SuperBraid NEVER broke or abraded through. I stopped after 100 passes. It looked barely rubbed. The line didn't start to "feather" or show strands. Like I said, not scientific, but the edge of my vise is pretty sharp, more so than most river worn rocks I've encountered. Braid looks better to me all the time.
