Trout Magnet SOS is a great co-polymer at a great price....if you are looking for nylon line. It comes in 2...4....and 6# test. A very manageable line....easy casting. The 2# test would most likely test out at 4# test. So I am sure that the 4 and 6# test will test out higher also. I wish lines made for US market would test out at what the line rating is but seems all companies rate them lower than they test. I fish with fluorocarbon straight through on one rod. It is 3# test Toray Razor out of Japan. It is a premium line but even at that you have to be careful when casting. The key in using fluro...IMHO....is to make sure the weight of the lure is enough to bring the line off the spool.....I can't cast a 1/64 ounce jig head with fluro.....it will become a birds nest. I also have one rod setup using 2# test NanoFil with a 2# test fluro leader. It is my go to setup for crappie and Gills. I have had a lot of success with it. These are my experiences fishing those lines casting.....don't do much vertical jigging.
