Have not had that problem with Triline and I buy it at Walmart or CT.
I now use PowerPro too and find it works well, however I have had it knot a couple of times on me.
My concern is that the PP scares the fish. Maybe I fish too clear of water to use it, but I'm sure I'm getting into the fish, just not getting them to hit and I wounder if its the line and not the bait.
