The 6/0 is perfect for streamers, pike or saltwater flies and other flies where you require inserting bigger materials! The thread is two-strand which makes splitting the thread to insert dubbing very easy & fast. Just unwind it a bit, give it some slack and it opens up on its own.
This premium 6/0 thread from Veevus in Denmark is stronger than many other comparable threads and will not result in excessive build-up. Good value for money with 100 meters per spool
