J3 coating update
Wulff has implemented a new coating "J3" the box and spool should indicate if your line has it. Billed as big improvment but pretty new still.
"Is it possible Wulff put the wrong line in the box or maybe some other quality control problem?
Unless the head profile has changed significantly, I wouldn't expect that much difference for the same rating?"
This could be. It might pay to try another of same class.
