I learned a lesson last year that I thought I'd pass along to you all. I was using braided line with a flat slip sinker above a swivel, mono leader and hook. I was fishing moderate current in a swirl (Miss. river) so the bait was moving quite a bit. I pulled in a eater and had a wad of fiber about 6' above the swivel serious enough to hold the sinker up while I was pulling in the fish. It turns out that the sinker had a metal burr on the ID of the hole that abraded the line to the point that only a few fibers were left intact. It was a miracle that I got the fish in the boat. It was a fresh rig - total time in the water was less than 30 minutes. Moral of the story - check the ID of slip sinkers if you're mainlining them on braided line and fishing current. Any sharp burrs could quickly cause some major line problems. It never occurred to me before, but you can bet I check my sinkers out now.
