i'm huge fan of the 12 lb Gamma edge. i've straighten out EWG hooks with it. but it is little pricy. for only 120yds

Seguar InvisX for me.

I like Sugoi and FC Sniper Sunline, they are both expensive but work very well for me.

Gamma Edge is the best fluro I've fished, bar none. Pricey but worth it. The BPS fluro is junk in my opinion.....I'd use it for a trip or two and it was done. Worked great when new, but not very durable for a couple trips usage. The Gamma is as tough after 10 trips as it is when it's new. The Cabela's brand fluro is made by Segar and workd quite a bit better for me than the BPS. My 2 cent...gary

I hate Berkley Vanish. I liked the Berkley Transition. I have not tried another fluorocarbon yet. I especially like to use this type of line as a leader. I strip my line too much to use only fluorocarbon line. It would be too expensive for me.

Check out Tackletour.com's Fluoro review parts 1 and 2 for some great information. Many of the lines mentioned above are covered. Also, I've used many of the lines mentioned above and I haven't found enough difference between some of the lower cost lines like BPS Fluoro and Cabela's No Vis (made by Seaguar) and the higher end lines like Gamma and INVIZX to justify the cost.
Some of the cheaper lines are stiffer, but there's not enough difference for me to justify the cost. I've got some Vicious on order and look forward to trying it out.

I'd recommend trying filler spools of a few different brands until you find line you're happy with.

MYTH - Fluoro doesn't stretch enough to throw crankbaits. Check out the Tackle Tour review and you'll see the average stretch for fluoros was almost equal to big game. Some stretched more and some less. Even the least stretchy fluoro line had over 6% stretch compared to over 9% for Big Game.

I'll add to the PLine and Berkley 100%. Both have been tough lines for me. One of my fishing partners likes the PLine Halo.

Just make sure NOT to use Vanish!!!

Vanish soured me on flouro. Used it a couple of times and hated it. Haven't used flouro since.

I've tried several different fluorocarbon lines.

For baitcasting gear here's my top three.

Sunline Shooter

Sunline Sniper

InvizX

For spinning here's my top two.

Berkley 100% Fluorocarbon

Sunline Sniper.

I've not been happy with any of the other fluorocarbon lines on spinning gear.

TFP

Gamma...the real deal

I've used the Vicious for a while now and it works great. It's a little stiffer than some of the most expensive lines, but not enough to bother me.

BTW - If you're going to use fluoro in a spinning reel, get the softest line out there or you'll hate it. I know the InvizX is very soft.

bps is as good as the more expensive, check out line or knot comparisons. most say bps is near the top.

The BPS is buy 2 get 1 FREE now so I'm thinking of giving it a try!?!?!?!? Opinions?

I just don't understand why anyone would put up with the stiffness and managability problems with spooling the whole reel with flouro.

If you want strength and no stretch, why not spool with braid and add a flouro leader?

You know.... I bought some Seguar Invisix in 15 and 20. I got a couple of prof. overruns but nothing serious. Then I put on a 1 oz. swim bait ($35) and gave it a fling and watched it fly beautifully with the wind about 60 yds. with 30 yds. of line. That swim bait had never been used. 1 cast and gone. This was brand new line on the first day of my very first trip to Amistad. I ran it 2 days and am still not happy with floro. Think I am going to braid with floro leader. I use it on the coast with no issues.
