Veevus Tyingthread
The Veevus thread is a really good, strong thread for all purposes and then Veevus is a Danish company. It's the strongest thread we've tried in terms of thickness. Comes in a number of good colors.
16/0 is for dry flies and nymphs
14/0 is a fine all-round binder for most things
12/0 is a bit thicker and stronger, fine for most things
There is 100 m on the spool
