if you can find it (epay) ... Berkley Ironsilk.... finer diam than most.. a reinforced Polymer..Very abrasion resistant... Came out about the same time braid became popular and it was exspensive .. about $35.. to spool up about ten years ago .. never took off .. Ive bought about 5lbs. of it .. great rock line ..
Before I knew anything at all - I used to fish rocks with the pink stuff all the time.
Chaffed, weather beaten and ancient it would still pull a horse out of the water.
I was shocked at the cast I got with half a spool of it.
