Re: Knowing when a line is too light?
The way I see it, and that doesn't always mean much, you have a few options
1. If you have the entire head of the line out of the rod and can't seem to load the rod still, then your line might be too light. (this assumes your casting is in good form and you aren't intentionally underlining to carry more line in the air)
2. common cents test on the rod and weighing the head of the line
3. Borrowing a higher wt line and casting with that. If that line feels better, your original line might be too light
