I’ve had a few hook lengths break, tied at 4 inches for method feeder and also for margin pole rigs, using thin line for hook lengths, either 6 or 8 pounds test, as these are mainly for carp, well I was looking at which lines I had to tie some hook lengths with, and tried some Preston reflow sinking feeder line in 8 pounds test, not been broken since, using it with my margin pole, with some middy hi viz pole elastic, rated at 12 to 16, had carp up to fifteen pounds on it.
I have this line on a couple of feeder rods, and it’s very good, not had any problems with it all, I might try the standard Preston reflow and see how that goes.
