Deep loading with smooth recovery, the Glass series has brought some serious soul back to fly fishing. Available in four-piece ‘Big Water’ series, which features additional power and longer lengths for the bigger water and bigger fish found out West. A rod’s power is its resistance to flexing under load. Powerful rods are ‘beefier’ through the bottom half, generate higher line speeds, and are more adept at keeping big fish pinned. Delicate rods are more presentation-oriented, protect light tippet, and are a better choice for picky fish.
