I don't fly fish in the fresh water, only the ocean.
I use a 7,8,9,10,12.
The 7 is loaded with clear intermediate. The 8 is loaded with floating wonderline. The 9 is loaded with 200 grain depth charge line. The 10 is loaded with some intermediate line and sometimes a depth charge, but I have no idea of the weight. The 12 is the "go to" rod with intermediate wonderline.
I have spools of line that I have no idea what weight it is.
I build all my rods too.
The past few years I only fly fishing at night.
Lately, I've been into long distance surf casting, which is now taking up a lot of my thoughts. I've become obsessed with reel tuning.
