I purchased this line to use for high country trout fishing on open water and through the ice. It's very thin and stays predictable at sub freezing temps all the way through to the mid summer heat. It posts minimal presence in the water. That allows me to catch the larger fish that are "too smart" to hit regular mono type of line. Expensive yes. But if you factor in all the other costs, good fishing line is worth the investment.
Love this line! Super supple for casting, virtually invisible with small diameter, and incredibly strong for the pound test. Highly recommended for any kind of finesse fishing. Great deal too!
Tried this line in a filler spool and was so impressed I bought a 1000 yard spool to put on my other reels. This line is smooth with little memory but is tough with a small diameter. I would recommend it to anyone who is interested in finesse fishing in clear water.
You can't beat seaguar line in general and invisx in particular, it is the line I spool on all my finesse rods and I wouldn't use anything else. The line casts great and it is virtually invisible under water yet it is very strong.
