I heard a lot of good things about this line is it that good?

Thick line with probably american breaking strength standards vs Sunline. I'd say it performs as needed - Does everything I need as a leader. This is coming from someone that stopped using straight FC anymore.

Very strong and hard to break. More memory than other FC lines and thicker for sure. A little less manageable in my opinion. But man that line is tough. Definitely has some uses. 

I tried it and it was ok.   There are other FC that handled better, had less memory and were thinner with the same knot strength.   It just didn't make much sense to continue using it. 

I use 6 lb Edge for leaders on all of my finesse applications.   It is very abrasion-resistant with good knot strength.   I have tried many other leader lines and the Edge is the best.  I plan on using 10 and 12 lb for leaders on baitcasters.  The line is a little thicker than others so scale down.

 

I also use Gamma Touch and that is fantastic line.  Straight 7 lb is what I use for small swimbaits on a spinning rig.  Manageable with good strength.  A buddy swears by 9 lb but that is too thick for me.   

Like others said, very strong and great abrasion resistance but also quite a bit of memory. Makes a good leader but using it for a mainline gets to be a hassle.

Ok then I'll stick with invizx and sniper. Those lines suit me well. I would like to try tatsu some time.

I used 10# on a baitcaster for a year. As others have said it’s thicker than most fluorocarbons. At 10# I thought it handled ok with line conditioner. Best part it was the most abrasion resistant fluorocarbon I’ve ever used. And I’ve tried lots of different FCs.

 

 Worst part is it’s more expensive PER YARD than Tatsu. 

Great for leader, I use it in 6, 8, and 10 pound test.
