Techstream GSP Power Thread Large 6/0 150D 100m

GSP threads are now available that push the limits of fly tying!

Power Thread is a GSP thread from Italy made from a state-of-the-art polymer that is 10 times stronger than steel of the same diameter.



The 150D (6/0) is the strongest in the series with a breaking strength of 5.6kg, but when squeezed, it is only about 20 microns thin.
The flat thread makes it flat when unraveled counterclockwise and thinner when squeezed clockwise, allowing you to wind flies neatly while using it in different ways.
Finely textured for less slippage than regular GSPs and better waxing.

Ideal for streamers for large, sharp-toothed game fish in saltwater, or for increasing the durability of large flies, such as patterns involving large poppers and weights.
It can also be twisted in the manner of a dubbing loop and used for blind eye hooks as an eye that is much stronger than silk gut.

Use with ceramic bobbin holders or hard polished stainless steel bobbin holders.
