The blank has SHIMANO's unique Spiral X structure, a three-layer structure in which the inner layer and outer layer of the vertical fiber sheet are wrapped in diagonal carbon tape to form a sandwich. A new dimension of blanks with diagonal fibers that also function as horizontal fibers.

By simply changing the structure, we were able to improve torsion/collapse rigidity without increasing weight.

The finish of the rod is surprisingly lightweight, and you won't notice its 14-foot length at all.

It has high sensitivity and is highly effective against twisting caused by Spey casting due to Spiral X, forming a powerful loop.

The slender, dense blank is less susceptible to wind effects and can produce stable loops even under adverse conditions.
