Used this thread for tying large salmon flies and found it strong and reliable. The thread lays flat and splits cleanly for dubbing. No clogging issues during use, which is a big plus for long sessions.
Ryan Mathis –
Great for streamers and predator flies. The 3/0 size holds well on larger hooks. It’s easy to work with and the wax keeps the materials in place without being too stiff.
Paul Davies –
Solid performance for deer hair spinning. The thread is strong and doesn’t fray. A bit harder to split than expected, but still works well for basic dubbing.
