Royal Wulff Sea Wulff Triangle Taper Intermediate Fly Line – Coldwater 75°F & Below
The Sea Wulff Triangle Taper Intermediate is built for fishing just under the surface and into the upper water column when a floater rides too high. This 105’ line uses a Triangle Taper Salt profile with a 30’ taper/head and a dedicated 10’ handling section for smoother line control and more consistent shooting. Its intermediate density sinks ~1.75 inches per second, helping keep flies tracking subsurface without dropping too fast. Finished in Aqua, rated for coldwater (75°F and below), and equipped with welded loops for quick rigging (front & back on 7–11 wt; front loop on 12 wt).

This line performs well in coldwater conditions. The 1.75 IPS sinking rate keeps my flies just below the surface, which is perfect for nymphing in clear streams. The handling section makes casting easier, especially in windy conditions. The welded loops are reliable and set up quickly.
Steven Turner –
I’ve used this line in temperatures around 68°F and it holds up well. The triangle taper gives a smooth cast and the line doesn’t tangle easily. Sinking rate is consistent and flies track well without dropping too fast.
Colin Stewart –
Great for intermediate depth fishing. The 10-foot handling section helps with control during long casts. I appreciate the durability and the way it performs in cold water. Set up fast with the welded loops.
