RE:largemouth on the fly
Actually, I usually load up the Sage with a 10, but a bug taper might cast better in the 9 [which the rod is rated for]. I do believe you can cut off a piece of the end of a weight forward line to get the bug taper. If I'm not mistaken, that's how the bug taper was developed in the first place.
Let me know if you get the line, I've got just the place to run a field test on it. It's a dirty job, but somebody's got to do it!
