We will conquer all the thick and deep flows! Ryuki 71S is a newly designed 70S based on the body shape and internal structure. Capturing mainstream trout = controlling all flows. The low center of gravity due to the trapezoidal design allows for stable swimming in all types of currents, and the first swivel eye reduces the risk of dislocation. Target all large trout such as Sakura trout, Satsuki trout, rainbow trout, and brown trout.
