Echo Boost Fly Rod Freshwater SeriesThe Echo Boost is a fast action rod that encourages tight loops and a quick casting stroke. Rajeff Sports designed the Boost to be stiff and powerful for long casts and large fish. Extra power, in the case of the Boost, unfortunately means more overall rod weight. The rod is heavy. But if youre targeting big fish, sometimes rod strength is worth a rod weight compromise. The series includes models for every fishing scenario from 2wt through 12wt. Are
