Well, on previouse posts, i've sung the praises of Daiwa sensor, but rescently I re.newed the line on 2 of my reels with sensor i bought from the fishing show at Sunderland last year, and it snapped about 30 ft away from the rod tip when i was fast up. Changed reels, and more or less the same thing happed again. I've heard reports of this happening, but dismissed it as probably a knick in the line, and now can't trust it.
