Just test it with a scale. It’ll start breaking at lower poundage as it fatigues. I had a couple reels full in Alberta start to fail around the ten year mark. I haven’t worn any out here in the coast. The pink line on the reel in the pic had that line on there when I bought it and he told me it was over five years old. Still tests good so I’m running it. This winter I put it on a new reel so it swapped ends but last March I had a wahoo all but spool me, he took over 800m on the first run at 30lbs of drag so it was certainly tested and took the strain.
Personally I prefer the J braid or suffix to anything else and always with a 60-100m mono top shot.
