NEW TECHNOLOGY - We’ve been busy behind the scenes as well. Recent upgrades to the equipment in our rod shop have enabled us to take advantage of the latest, cutting-edge graphite composite materials, which — along with new rod designs — make our product launches for the 2016 tackle year especially exciting. The new materials not only bring marked advances in performance and durability, but our new process also enhances the feel of the blank, with an improved connection between angler and fly, for a rod that truly feels like an extension of the arm.

From RIO:

The "A" rating is for more experienced casters, or for casters that like to cast off the tip of the rod. It is also a good choice for longer rods and wider rivers where the caster can carry the whole head length of the line outside the rod (55 feet in the case of most WindCutters). The "B" rating is for less experienced casters, and for casters that like to feel a deeper load in the rod. It is also a good choice for coping with tough winds, or using larger flies.
