i use 4lb red label and can't believe the difference between it and 6lb.  every time i touch it i swear it's 2lb. as mentioned knots and abrasion are a sensitive subject w/ 4lb.  i use a super sticky fine wire hook: Do-it Wireguard Wacky Jig 785. it's supposed to be for a flick shake jig mold but i just use it bare.  it's sorta EWG w/ 60 deg eye so you can perfectly skin hook a Zoom finesse worm or 2.5" tubes. i think someone told me they are Mustad hooks. maybe someone can confirm.

i learned the hard way to not put rod pressure on a bass with that light of line.  if he makes a run while ur pulling with the rod it's game over (tho i was using heavier hooks and had too much drag set).  you can also back reel.  don't be afraid if she runs b/c the drag system still works even while back reeling

They are Mustad. Check the points, they roll easily.

^good to know.  for .09c a pop i'll keep a close on them and toss'm when compromised.

maybe someone will recommendation a better one

Seguar red label fluorocarbon is the same diameter as a line 2lbs weaker than it. So 6lb is the diameter of 4...4 is the diameter of 2...you get the picture. So if you are wanting to fish light, go with that. Have to be careful with light fluoro when tying knots though.

Due to past experiences, I won't fish 6lb and under on anything but small, exposed hooks. I use #2 gamakatsu drop shot hooks when I use light line.
