Super thin high quality flouro. Excellent for stealthy saltwater fishing rigs!I’ve been purchasing Seagar Blue and Premier Flouro line for many years. It’s simply the best IMO. When I found this Tatsu line, it looked like it had the same line diameter and strength as Seagar Premier at half of the price. Considering how many Pompanonrigs I tie, that’s a good thing.I used it to tie about 25 Pompano rigs using a Snoot (dropper loop rig with one end cut) as my dropper line. I then place a float on the line and snelled my hooks to the end. One the top end of the rig I used a figure 8 loop to attach the rig to my main line. At the bottom of the rig I tied on a snap swivel to attach a pyramid weight.These rigs are quick and easy to tie and they are super stealthy. I caught a bunch of Pompano and for the most part, they performed very well. I say for the most part because several did break in normal conditions. Yet, some rigs were so strong that I was able to drag in some very large drums and stingrays.The question about durability is still open. Some rigs seemed to break way to easily. I must say that this could be because I did a poor job tying the knot or I simply didn’t lubricate it enough when cinching it tight. I had rigs break in weird ways, but I’ve seen this with even the most expensive lines. Catfish with sandpaper teeth could also compromise the line if they swallowed the hook. Again, this is true even with mono.Amazingly, A few Pompano pros asked me how I was getting so many bites when they weren’t. I pointed them to this line. None of them had ever heard of it. Many asked if I would loan them one of my rigs. One went exclusively to this rig type I er a rig that they had tied and used for many years. It works!So, in synopsis, this line is high quality very stealthy, super thin Flouro line. It not only caught me a lot of fish, I was regularly getting higher quality fish than the people I fished with. Is it better or equal to Seagar Premier? I cannot answer that yet and I don’t know that I’ll go through enough effort to determine this.Realize that when you fish with super light line in saltwater, you’ll get way more bites, but you’ll also break a few off. The breaking strength of a dropper loop rig is known to compromise line strength! In the end, you’ll need to decide if losing a few rigs is worth getting more bites.I highly recommend this line. My only wish is that it came in line strength up to 60#.
