Fc rock 4lb and 6lb.
Great product. Bought online and shipped fast.
4lb is sensitive to the type of knot.
I usually tie a 5turn improved clinch but it was breaking really easily.
After loosing 2 medium fish, I spoke to a few bream anglers who swear by fc rock and they recommended a 3 turn uni knot.
For whatever reason the 3turn uni is better for this line in 4lb.
I then tested it by tying on a hook and hooking it to a chair and testing. Very very strong for 4lb and the bream seem to respond better to this thinner diameter.
It was very close to being a negative review just because I wasn’t aware of knot impact on thinner diameters.
