Welcome to the latest edition of our weekly trivia challenge, in which we test your knowledge of all things fly fishing and where you might learn a thing or two about this sport we love. This week, I’ve ginned-up a new quiz, with ten questions guaranteed to make you furrow your brow. Some are quite easy, while others are surprisingly tricky.

The last quiz must have been about as difficult as the one before, for we again had just one perfect score, which belonged to Steve. He was well ahead of the pack as there were no 95% or 90% scores. The most common score plummeted to 50%.

The winner of this week’s random drawing will receive Jay Zimmerman’s great new book The Best Bass Flies: How to Tie and Fish Them, from Stackpole Books. The book features 18 cutting-edge patterns from around the country for largemouth and smallmouth bass, explains how to fish them, and has detailed tying steps.

The winner of our last quiz (as determined by random.org), and recipient of a copy of Tom Rosenbauer’s The Orvis Guide to Hatch Strategies: Successful Fly Fishing for Trout Without Always Matching the Hatch, was Dave Driscoll, who just a bit above average.

So post your score below for a chance to win a great book.

Good luck!
