Royal Wulff Midstream TT Intermediate Fly Line
The Midstream TT Intermediate is a versatile subsurface line built on the Triangle Taper Classic design for smooth energy transfer and easy casting—especially roll casts and quick pickups. With an intermediate sink rate of ~1.5 inches per second, it keeps flies tracking just under the surface and into the upper water column for nymphs, wets, and streamers. Specs include a 90’ total length, 36’–40’ taper, 50’–54’ running line, Aqua color, and a front welded loop for fast leader changes.

This line performs well in both roll casts and quick pickups. The sink rate is just right for keeping flies near the surface without sinking too fast. The triangle taper makes casting smooth and predictable. I’ve used it for nymphing and streamers with good results.

The aqua color is visible in the water, which helps with tracking. The loop is easy to use and stays secure. It’s a reliable choice for intermediate fishing conditions.

I appreciate the consistent sink rate and how well it handles both slow and fast casts. The design feels balanced and the line doesn’t tangle easily during use.
