Diamondback Generation IV Nymph series is engineered for anglers who demand precision, finesse, and versatility in their fly-fishing pursuits. Designed by Diamondback rod designer Joe Goodspeed. With a range of models tailored for ultralight Euro-nymphing applications to heavy-duty steelhead and salmon fishing, this series offers a rod for every scenario. Each rod is engineered with a specialized action profile to optimize presentation, tippet protection, and fish-fighting capabilities while maintaining superior sensitivity and control.

Available in 10’ and 10’7” lengths for extended reach and line control, the Generation IV Nymph rods are designed to balance perfectly with appropriately matched reels for fatigue-free days on the water.

Available with both cork and carbon grip.

Eight models available:

• #1, 10'0": Joe Goodspeed designed the Generation IV 10' 1wt to be the ultimate finesse tool for the lightest leaders, smallest nymphs, and spookiest fish. It will load and recover under the weight of the rod itself, allowing you to deliver lightweight flies with ease. This action profile performs best hooking and retaining small and medium sized trout while protecting fine tippets, but has the backbone to fight the occasional larger fish as well. Optimal fish target size: Best for fish under 18” / 45cm. Optimal AFTMA line weight for casting: Not designed to overhead cast, but will load with the smallest floating lines or level floating line .022-.025”.
• #2, 10'0": Joe Goodspeed designed the Generation IV 10' 2wt to be  finesse tool with the versatility to cover most light nymphing work and some overhead casting. This rod loads easily and with small to medium sized flies or multi-fly rigs on micro leaders. The 10’ 2wt model will cast overhead with a true 2wt fly line and single dry or nymph. For dry dropper style fishing or indicator work, the 3wt models are a more suitable choice in Generation IV nymph rods. Optimal fish target size: Best for fish under 21” / 55cm. Optimal AFTMA line weight for casting: Lines that fall within the AFTMA standard for 2wt lines will be the best match, but 3wt class lines will load the rod more easily when most casts are going to be short.
• #3, 10'0": Joe Goodspeed designed the Generation IV 10’ 3wt to be a highly versatile tool that will cover a wide range of applications and techniques. This rod loads easily with light to medium weight multi-fly rigs on micro leaders or heavier leaders, and fishes well with a jig streamer up to hook size 6 or 8. The 10’ 3wt model will cast overhead with a true 3wt fly line, and has the perfect action for fishing dry-dropper rigs. It will also handle small indicators with nymph rigs too heavy to support with a dry fly. This is a great rod model to choose when larger fish are in the mix, but you still need small flies and precise presentations to fool them. Optimal fish target size: Best for fish under 25” / 64cm. Optimal AFTMA line weight for casting: Lines that fall within the AFTMA standard for 3wt lines will be the best match.
• #1, 10'7": Joe Goodspeed designed the Generation IV 10’7” 1wt to be the ultimate finesse tool for the lightest leaders, smallest nymphs, and spookiest fish. It will load and recover under the weight of the rod itself, allowing you to deliver lightweight flies with ease. This action profile performs best hooking and retaining small and medium sized trout while protecting fine tippets, but has the backbone to fight the occasional larger fish as well.

• #6, 10'7": Joe Goodspeed designed the Generation IV 10’7” 6wt to be a versatile tool that will cover a wide range applications and techniques for Steelhead and similar size fish. Migratory freshwater and saltwater trout, Bull Trout, Alaska Rainbows and smaller salmon, Carp, European Huchen, and also handling the largest and heaviest jig streamers for big trout are all a perfect match for this rod model. The 10’7” 6wt has a great action for fishing weighted flies or bouncing bottom with incredible sensitivity on mono rigs, while also effectively casting a floating fly line with an indicator rig or shooting head system. This model has the backbone for the biggest great lakes Steelhead and most West coast Steelhead, with a powerful bottom end to help steer and turn big fish in current. Optimal fish target size: Best for fish under 18 pounds / 8.2kg. Optimal AFTMA line weight for casting: Lines that fall within the AFTMA standard for 6wt lines will be the best match. Shooting Head weight 250 – 275 grains.
• #7, 10'7": Joe Goodspeed designed the Generation IV 10’7” 7wt to provide the power and backbone necessary to target the meanest and biggest fish that swim in rivers. King Salmon, big chrome fall Steelhead, Hucho, and Taimen are all fair game with this rod model. The 10’7” 7wt has a great action for fishing weighted flies or bouncing bottom with mono rigs, while also effectively casting a floating fly line with an indicator rig or shooting head system. This model has the backbone and wall thickness to put some serious pressure on a big fish, with a powerful bottom end to help close the deal at the end of the fight. Optimal fish target size: Best for fish under 10 pounds / 4kg. Optimal AFTMA line weight for casting: Lines that fall within the AFTMA standard for 7wt lines will be the best match. Shooting Head weight 300 – 325 grains.
