Vision Big Mama Pike Fly Line - The Vision Big Mama is the perfect range of lines for bulky and heavy flies. The profile is a reverse compound taper with a short front taper to cut through wind. It has a slick and supple coating which remains memory free even in cold conditions. The low stretch core helps you to feel the takes and set the hook and transfers casting energy better than traditional cores. The ready-made loops make it easy to attach the leader and backing. Phthalate free.
