I'll use Red Label for line that I change often (12 lb for cranking) and InvizX for heavier more "contact" baits. (17-25 lb)

Seagar AbrazX

Invisx on my worm/jig and Red Label for cranks/spinnerbaits. Very few breaks with palomar knot.

I like the Sunline flouro (Assassin or Sniper) is what I use. Only use it on feel presentations. Moving baits I just use a mono or a copoly. I see no benefit for flouro on moving presentations. Just be careful tying your knot and check for knicks and kinks often with flouro and you should be OK.

Seaguar Red Label is garbage IMO. It breaks in my spool, has memory, etc.

Now Invizx, I love, at least in 12 lb. I got an 8 lb box the other day and it broke (mid-line) in my spool a bunch of times the first day. Maybe I just got a bad batch, because the 12 lb has never done that to me.

Sunline sniper

Invisix. I would probably love Tatsu, but it's a little pricey for my budget. Wetting your knot sufficiently is key. I never cared for Berkeley FC, but never had an issue with BPS

This is one of those loaded questions, like do you prefer Ford, Chevy, or Dodge trucks.
But I will put my 2 cents in anyway...I prefer Shooter or InvisX.
They provide me with good middle ground...not overly expensive and adequate strength.

Tatsu or AbrazX but to be honest I've just about switched all of my reels to braid w/leader. Using 6 -10 ft at a time makes the cost not so bad.

Zero problems with red label. Use a quality line conditioner. 12,15,20lb

Looks like ya got enough votes....but one more for InvisX. I've pulled logs up from the bottom to save hooks and tungsten. HARD to break.

I've never used red label but know lots of guys used to, was it better when they used to level wind it?

I'm a big fan of Invisx, I have never had a break off. Then again, I'm not much of a fisherman, I hardly ever catch fish.

vanish 4lb test is all you need
