Hi William
Sorry for the late reply
I missed this post.
Nice rods
.... I wouldn't get too hung up with line choice, these rods were pretty versatile. I'd start off by trying any WF7 line that you have, you should find it is happy with that.
But try a WF6 and a WF8 too, it is always good to try a line weight up/down with all rods, as these things are very much down to personal preferences
Cheers
Mike
