Team U.S.A. member Pat Weiss is one of the best river fishermen in America, and he has been for quite some time. His BP series, which comes in both dark and light, is a killer perdigon! While it's designed to imitate baetis nymphs, we love fishing this bug, and others very similar to it, 365 days a year.
Here's what Pat has to say: "My BP (Baetis Perdigon) is just a clean, simple, durable Perdigon pattern. Danville threads used in the construction of this pattern really set these apart from most as the thread seems to glow when resined over. No flash for a natural looking bug. Super slim and clean for quick sink rates which is immensely important with this type of fly."
