Anglers have been trying new things for as long as fishing has been around to find ways to increase their 'luck'. Spin and casting fishermen have been quite open and willing to try different lures, methods, and products if it promised better success. Fly anglers on the other hand, are often much slower to accept something that is non-traditional. When was the last time you watched a fly fisher soak their fly in some liquid containing 'scientifically proven pheromones' that is supposed to drive fish so crazy that it will attack?
Of course, fly tyers are always open to new materials to tie flies with. Those of you who are not familiar with the Rubber-Band fly might want to take a look to see the creativity (or perhaps lack thereof!) of one fly tyer. Some fly anglers might turn up their noses at such non traditional methods, but others figure that if it works, why not?
Jean-Guy Cote, president of Uni Products, probably fits into the category of fly tyers that believe there is always something new to be discovered and used to catch fish. As Izaac Walton said,
"Angling may be said to be so like the Mathematics that it can never be fully learnt;
at least not so fully but that there will be more
new experiments left for the trial of other men that succeed us."
This brings us of course to Jean-Guy's new product. Will it revolutionize fly tying? I doubt it, but it sure could add a great deal more fun to the sport as spectators stand and watch us holding our flies in front of flashlights, headlights, and latterns! I am sure Walton would have an expression or phrase for the thoughts of on-lookers that think of anglers as being a bit daft.
According to Cote, Uni Products new Glo Yarn will glow for up to three hours after it has been 'charged' with a light source. It's a great attractant and may be used on any part of a fly. I am sure that many creative fly tyers will think of many uses for this stuff.
I haven't tried any flies with Glo Yarn yet, but I did check out its glowing abilities. I simply charged the spool with a camera flash, and took the spool into a dark room. Sure enough, the spool was glowing! I can definitely see where this yarn could be very effective.
Just make sure that when you ask your friend to 'flash your fly' that they understand you mean fishing fly... not the zippered types.
