Viewed next to other 6-weights, I initially noticed the NRX was thicker near the butt and worried that the rod would be overkill for smaller fish or delicate presentations. But what I found was that though the diameter was larger, the lightness of this rod balanced it out. The mid-flex did not overpower smaller fish that ate nymphs, and the sensitivity of the blank really telegraphed every tick off the bottom and subtle strike. The stiffness also helped make a tighter, faster mend in heavy current. At the same time, the thicker butt turned over heavy dumbbell streamers and a sink tip with the power of a 10-weight. According to the company, their 6-weight was developed with bigger flies in mind, though considering the distance it will produce, I'd still use this rod to launch dries on any river where trophy fish abound.
