I am looking for a true to grain weight saltwater fly line. In particular something in the 6wt or 7wt category. I know this seems like a tall order. I have searched and I have found that most modern fly lines are poorly labeled, and most are one if not two lines classes higher than what it printed on the box. Do you have any recommendations? I am hoping to take an 8' 6/7wt to the Texas coast for Speckled sea trout and maybe smaller Red fish. The rod in question is not necessarily picky about fly lines, but I am sure if the line is actually grain weighted as a 9wt it might have problems. Thanks in advance for all of the help.

If you are going any time soon the water is going to be WARM and that makes a difference. There are a number of "tropical" WF6F & WF7F lines that will work for you.

I always used the old SA Mastery Bonefish lines, and they worked very well. As mentioned, the line needs to stand up to hot temps, at least in most cases.

The lines called "salt water" are really "hot weather" lines with stiffer coatings and cores. In the North East the sea water is cold, the air is cool and most of the "bass"/"trout"/"fresh water" lines work well. An SA line designer recently told me that one of their "salt water" lines would be best suited for our Ozarks summer warm water fishing. He said that he uses tropical lines in Mi. bass fishing in summer heat.
Point being that any line you like in our 100F days for warm water should fish there just as well.
Cortland and SA both have true weight lines on their websites, although I think that doesn't matter much unless you just fish at 30'. Rio is right now in the middle of website redesign and info on their lines has to be found on third party sites.

I find the deviation from the standard becomes very noticable once you get to "10 " at or greater. I note this in my survey at

Mike, I’m an old man now - can’t cast for crap anymore, shoulder surgery and just much weaker than I used to be. I have found the Quickshot line (mfg?) is what I like now. Short heavy head and thin running line. With 25ish feet of line out it is not hard to shoot to 40 feet or more - sufficient for most salt situations if you are stealthy.
