Re: what weight spey line
One thing I was trying to point out is that the rod is mis-labeled! It says 5wt, but for a WF line it takes a 10 or 11 wt line to load the rod. I tried an 8wt (WF8F) line and it wasn't heavy enough.
My best guess is that it's somewhere close to an 7/8wt spey since it requires about 3 sizes heavier (10/11) for overhead casting.
