"Caddis are most vulnerable to predation during their pupal and emergent stages. This where the Nitro Caddis Pupa comes in. With its dynamic light shifting properties and 'sticky sharp' TMC 2499SPBL hook this one works. The NITRO is heavy enough to get down and stay down until the swing towards the surface at drift’s end. Since its origin in 2005, the Nitro has been a top producer for me both East and West."
