The Blob

Advocates for traditional fly-fishing want to ban the blob fly pattern, considering it unsporting. Unlike traditional flies crafted to imitate natural forage, the blob, with its flashy appearance, was designed to trigger trout and is seen by many as an unfair advantage in competitive angling, making trout fishing too easy. Former England fly-fishing champion Chris Ogborne even left the national team in protest against the use of blobs, labeling them as cheating. He argues that the reliance on blobs undermines the core essence of fly-fishing, which traditionally involves imitating a trout's prey with hand-tied flies made from natural materials.
