The Olive Francis Conehead Salmon Tube Fly is a modern, weighted variation of the classic Francis pattern. Tied on a tube with a conehead for extra depth and movement, it features an olive body, tapered feelers or feeler tails, and subtle ribbing that gives it a natural shrimp-like profile. This fly sinks quickly and performs exceptionally well in strong currents or deeper pools, enticing salmon that are holding low or reluctant to rise.
