the line fraying will also depend on what you don't see and how you fish. let's say you are fishing a 20' deep part of a lake that has some rather strong weed growth (plants at about the 8' tall point) and you are dragging a lure through it. I wonder how much damage that will do to your line rubbing on all those weeds? also, rocks and zebra mussels as well. if you fish downed trees, the same question, how bad is the line getting beat up? I look into what I'm fishing with and how before I say something like it 'frays a lot' because you (everyone) and I don't fish the same way. I look at what/when/where/how when I give a review on something because your Subaru might not drive like my Subaru does even if they are the same car made 2 days apart.
I look at shape of the line because it helps in casting farther if round and how often I have to re-tie because of how I fish. other gear like rods and reels are not much of a factor now will all the new gear because the new $20 rod is using 1 to 2 year old technology from the $100+ rod the same company makes. just check on your gear to make sure that it's not damaged...
there, that's my 2 cents for ya...
