Victor Brown –
Used this thread for building larger trout flies with stonefly patterns. It holds well under tension and doesn’t stretch when tied. Much better than 50D for bigger wings and legs.
Austin Burgess –
Great for tying Marlin and GT streamers. The thread stays strong and doesn’t break during casting. Low stretch makes it easy to secure tight patterns.
Adrian Lewis –
Solid performance for larger flies. A bit stiffer than thinner threads, but the strength is worth it for durable patterns in windy conditions.
Kylie Newman –
Used it on a hopper pattern with synthetic wings. The thread held up well and didn’t slip during casting. Very reliable for tough materials.
