Generation IV Nymph Specifications

Generation IV Nymph 10' 1wt

Rod weight: 3.15 oz / 89 grams 
Reel Balance weight (for empty reel, assuming 1oz backing and line, to achieve roughly 60 degree tip up balance from hold point): 5.0 oz / 142 grams

This rod model will perform best for fishing situations that fall within these parameters:

Optimal hook size range: 14-26
Optimal tippet range: 6x and lighter 
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”

Rod Application Description: 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.

Generation IV Nymph 10' 2wt

Rod weight: 3.35oz / 95 grams
Reel Balance weight (for empty reel, assuming 1oz backing and line, to achieve roughly 60 degree tip up balance from hold point): 5.2oz / 147 grams

This rod model will perform best for fishing situations that fall within these parameters:

Optimal hook size range: 12-24
Optimal tippet range: 5x-8x
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.

Rod Application Description: 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.

Generation IV Nymph 10' 3wt

Rod weight: 3.4 oz / 96 grams
Reel Balance weight (for empty reel, assuming 1oz backing and line, to achieve roughly 60 degree tip up balance from hold point): 5.3 oz / 150 grams

This rod model will perform best for fishing situations that fall within these parameters:

Optimal hook size range: 8-20
Optimal tippet range: 5x-7x
Optimal fish target size: Best for fish under 25” / 64cm

Rod Application Description: 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.
