Know your knots, and know them well.
There are probably about 1,000 common knots when it comes to fly fishing, and I know like 3.
I only know 3 because I only need to know 3. And the 3 I know are not superior to any of the others really, I just decided to learn a few and stick with them.
In my early fly fishing days, I wasted more time on the water, and lost more fish, than I care to mention because I sucked at tying knots. A few of those days on the river will teach you a lesson that you’ll not soon forget. It will also teach you to take the time to learn knots better.
These days, I’m fairly proficient at tying knots. I’m pretty confident with them, and I know that rarely will my knots be a point of failure any more. By learning just a few, and sticking with only those knots, I’m completely confident in them now.
The knots that I know are not even important, as there are hundreds that will do the job just as good. What is important is knowing them and being confident that you can tie them well, no matter which knots you choose.
Learn a few knots and be completely confident with them. It will save you time, it will help you land more fish.
