What's your favorite line and why?

I have used Silver Thread AN-40 since the early 90's when it was Bagley's AN - 40. Its the best I have used and I have used them all at one time or another

Invisyx

Invisx

Invizx. It casts well, and it is strong.

Considering price/availability

Favorite Copoly--McCoy's
Favorite Fluoro--Seaguar Red Label
Favorite Mono--Big Game
Favorite Braid--Power Pro

Bass pro KVD floro or Vicous Pro Elite only

I use only Seaguar. I bounce back n forth between Tatsu, Invisx, and Red. If I'm fun fishing, I will use Tatsu, since I can spool it and leave it on for a while. If I'm Tournamnent fishing, I will respool A LOT, and will not justify Tatsu money for a day of fishing and I will carry 15-20 spools of Invisx and respool every reel used every night in the hotel. If it's in "a pinch", I will use some Red label since it's available just about anywhere, including Walmart.

Get Invisx. It's the best for the money. Period.

Edit: forgot to add why I like it....

I like seaguar because it's level wound on the spool and that makes it a very smooth line with great uniformity. This helps it cast really well and I also like the knot strength. The Invisx is a softer line and has pretty low memory for a flourocarbon line. Just have to be careful around hard structure and retie the lures often. The Tatsu is the very best I've ever used. It has low memory combined with great abrasion resistance and great knot strength. It's just expensive at about $40 for a refill spool. Too expensive to respool after one days use.

I have tried other flourocarbon lines. Mostly looking for a cheaper alternative. Just haven't found one that is as good for the money. So I keep buying Seaguar.

Hard to beat red label for the price. Get some line conditioner for it. Invisx and sunline are good too

Sunline for me, price, availability and just really like how well it casts and how tough it is. I did just buy some vicious elite that I am going to give a shot on my shallow diving cranks.

I used to use Invisx but then I started having problems with it so I switched to Bass Pro's KVD fluoro and have been very happy with that. To be honest, the Invisx problems were probably partially my fault because I didn't take care of the line like I should have. You can't go wrong with either brand.

One day I was in a bind and couldn't get to BPS so I grabbed a couple of spooks of Invisx from Academy. One spool had less than half of the line that it was supposed to have on it. I know that was an Academy issue but it was just another bad thing I associated with Invisx.

Invisx or red label

Invisx

I agree for a copolymer, but straight flouro I use XPS big spools for cost savings. Flouro is expensive and I try to save when I can. 14lb and 20lb is the two I buy. Just bought two big spools. $79 and $89 a piece but should last me a good while.

Trilene 100% flouro is the strongest out there by far but it gets chalky after awhile and its stiff. Tatsu is pricey but has smaller diameter than any of the others but it doesnt last long. I hate invisx it breaks on the hookset on me too much.
