Yes, 20# test, 4# diameter. Daiwa Samurai braid is thinner, and is also an 8 strand braid instead of 4. Very smooth stuff. The reason I went with the Samurai braid is because the reel is a 50e, and the amount of line going onto the reel is an issue with bigger lines. I just worry if the thin diameter of the line is going to cut into guides, or if it's just too thin for the rod (which specs are 10-20 # line. Also if I step up to 30# test instead of 20#, would it also be wise to upgrade in leader strength, instead of 10, since it's a pretty stout rig, use something like a 12-15# test leader?.
