This is the chart Official AFTMA (American Fishing Tackle Manufacturers Association) fly line grain weight specifications.....based on the front 30' of the line. Our website then tells you the grain weights for each line in the description for comparison. That will tell you whether a particular line is true to size or overweighted.
If you have any questions on selecting the right line for your needs, and your rod, feel free to give us a call at the shop. Helping folks is what we do!
