on my crank bait and spinning rods i will use 8 to 10 lb and for like jigs and worms and such i will use anywhere from 12 to 15 lbs. have not had any proublems. and i use a regular palymer knot. i hope this helps alot of people will use heavier line but this works for me. remember to check the line every so often and retie you should be fine. i like to use p-line 100% fluorocarbon or halo. i will also use fluoroclear. never had any proublems out of p-line stay away from vanish. the new berkley 100% fluorocarbon is good to. another thing is i like to use the KVD lure and line conditioner. i hope this helps.
