Neil Mills –
The floss is strong and consistent. I used it for my Salmon patterns and it held well in the water. The 50-meter spool is convenient for regular use.
Rachel Bower –
Good quality thread that matches well with my existing fly patterns. A bit thicker than expected, but works perfectly for the head colour.

Easy to tie and holds up well during casting. The polyester base makes it durable and resistant to water wear.
