Big flies for big fish isn’t an unusual concept.
The logic behind using big flies is to get larger fish to bite, while simultaneously weeding out smaller ones. At the same time, big flies imitate high-energy meals, which is enough to draw large fish looking to expend little energy.
This technique works in big rivers such as the Deerfield and Saco (both known to produce big browns) and even small streams. It is a low-volume technique.
I tried this technique recently during a brief evening trip to a small stream. I started the day throwing dry-droppers and picked up a few brookies. However, the dry-fly bite didn’t materialize like I thought, even with the warm weather.
With only a half-hour of day light, I tied on a white crystal Woolly Bugger. Over the next few minutes I went one-for-four, all six- to 10-inch brookies. They struck and fought hard.
I’ve heard rumors of even larger fish in this stream. Unfortunately, I got no other takes, and I had to leave, as it got dark. I may return in the near future with a few more streamers in hand.
