I purchased a spool of P-Line 100% flouro the Shinsei series. I am very disappointed in what I have experienced so far. Fished for 4 hours getting 6 solid hook sets and landing only 1. 4 times the line broke upon setting the hook while fishing plastics and once was when a bass exploded on a top water lure. The shock seems to man handle this line. Spending 10 dollars on a leader material to lose almost 20 dollars in lures has indefinitely steered me away from this line. I've never had any problems with P-Lines Mono's so the poor performance from their flouro is a shock to me.
If anyone else has experience with this line please put in your 2cent. I am open to the possibility of a bad batch but at 10 dollars for 25 yards, you would think their Quality Check would be stricter than this.
