Flash fibres are an essential part of most patterns of pike flies, the trouble with most of them is, they don't last five minutes! When I found this stuff and used it for the first time, I could not believe how tough and durable it is. It is the only fibre that I have ever seen that will withstand a good brushing without showing signs of wear. It is so strong that it will outlive most of the rest of the dressing! Add that to the fact that it is so reflective and will blend with any other material and you will see that it is the no. 1 choice for the construction of predator flies. We have several colours to choose from, and we intend adding more as and when they become available to us. THE BEST FLASH BY FAR! SPECIAL OFFER - TEN DIFFERENT FLASH PACKS FOR £15.00!
