Dodge, Grand Match is spot on in the diameter and breaking strains stated on the spools. Its won that test in every mag over the last 10 years where true diameter and strength are concerned. Its very supple for a fluorocarbon line. I,ve only seen one fluorocarbon line thats better on suppleness(Pro-micron, fluorocarbon). The line in a glass of water test convinced me to try the line in clear water conditions where the line might give me an advantage over other types of lines in difficult clear water conditions. I,ve done the glass of water test with other fluorocarbon lines and Grand Match wins that test out of sight. Sorry about the pun. Grand Match is almost invisible in water! The final thing that impressed me was the lack of weak points on the line created by shot. Fluorocarbon is hard and does not get crushed by shot like other lines. Always useful when fishing with light lines for big fish!
Oh, and i catch plenty with it in very difficult clear water conditions!
