RIO King Splitsville Megaspinner – Large Spinner Trout Fly

The RIO King Splitsville Megaspinner is designed for trout that are keyed in on large spent mayflies after heavy hatches. While spinner falls are often associated with smaller flies, species like Hexagenia (Hex), Isonychia (Iso), and Green Drakes produce large spinners that trout will sip confidently when conditions line up.

Built on Jonny King’s proven Splitsville Spinner platform, this larger profile excels during calm water and low-light periods when trout feed selectively on spent adults drifting helplessly on the surface. When fish are ignoring everything else and sipping quietly, the Megaspinner delivers the size and silhouette needed to match the hatch.
