Rachel Jackson –
Used this thread for tying dry flies and nymphs. It lays flat and splits cleanly when needed for dubbing. The wax holds well without gumming up the bobbin. Strong and consistent performance on hook sizes 8 to 12.
Stephanie Parsons –
Great for streamers and predator flies. The two-core design makes it easy to split for dubbing. No clogging during use, and the thread remains strong even after repeated tying.
Boris Rees –
Solid thread for salmon flies. A bit stiff when first pulled, but settles well. Works well with hook sizes 6 to 10. Slightly more wax than expected, but not a problem in practice.
