The RSII, also known as the Sparkle Wing RS2, is a highly regarded fly pattern used specifically for imitating small mayflies in fly fishing. It was created by Rim Chung, a renowned fly tier and angler.
The RSII - A Top Fly Choice for Colorado
The RSII is commonly employed when fishing during non-hatch periods when mayflies are not actively emerging. It can also be effective during the early stages of a blue-winged olive (BWO) hatch. This fly pattern is known to mimic the emergent or dun stage of mayflies.
The RSII is typically fished deep in the water column, making it an ideal choice for nymphing techniques. Anglers often use it as a dropper fly below a larger or more visible attractor pattern like a San Juan Worm, blood midge, or egg pattern. This combination can entice trout to strike the RSII as they feed on or near the riverbed.
As a hatch intensifies, the RSII can still be effective when fished as a dropper fly, particularly when paired with another mayfly imitation. Positioning the RSII at a mid-column depth creates an enticing opportunity for trout to rise and feed, making it an effective fly pattern to target selective trout during hatches.
RSII Fly Pattern Design & Imitation
The RSII (Sparkle Wing RS2) is a versatile fly pattern that imitates small mayflies, making it an effective choice for fly fishing in various situations.
The RSII typically features a slim and sparse design that closely resembles the shape and profile of small mayflies. It often incorporates materials such as goose biots for the tail, dubbing for the body, and a translucent or sparkly wing material.
The RSII is primarily used to imitate the emergent or dun stage of mayflies. In this stage, the mayfly has shed its nymphal shuck and is floating or drifting on the water's surface before taking flight. The RSII's slender profile and wing materials mimic the delicate appearance of these emerging insects.
It's worth mentioning that the RSII's success can vary depending on specific river systems, prevailing insect hatches, and the behavior of the trout in the area. Consulting with local experts, such as experienced fly anglers, fly shops, or fishing guides, can provide valuable insights into the best techniques and variations of the RSII for your target waters.
Fishing Techniques and Presentation
The RSII is commonly fished using nymphing techniques, particularly when targeting trout in deeper water or during non-hatch periods when mayflies may not be actively emerging. It often fishes below an indicator or as a dropper fly below a larger attractor fly.
When fishing the RSII, it is important to consider the depth at which the trout are feeding. Adjusting the weight of the fly or adding split-shot to the leader can help get the RSII to the desired depth. Additionally, the RSII can be used in tandem with other mayfly imitations to create a more realistic presentation during hatches.
