Our Amazon Associates link for the Fly Fishing Bible of Nymphing (containing a detailed spotlight on indicators - in both video and full-colour illustrated text) will also help you unlock many more nymphing secrets: https://amzn.to/3yPuutw Although I often like to use Sighter Tippet for Euro Nymphing (especially the black and white versions), there are some light conditions where the water is very silvery and the sighter (indicator) is impossible to see. The great advantage when using a French leader or Mono rig (or especially a Spanish Nymphing Leader) is that you can extend your reach while holding everything off the water - right up to where the tippet cuts through the surface. This means that your sighter material is, ideally, held off the surface too - so it does not interfere with the natural drift. It also greatly helps in keeping contact with your nymphs - making both bite detection and your hook-set much more effective. So, the challenge in difficult light is to add something that is extremely visible - but also weighs almost nothing. Old school worm (and fly) fishers used to use tufts of sheep's wool (collected from farmer's fences on the way to the river) as a kind of yarn indicator. In modern Japanese keiryu (mid-size mountain-river) fishing, it is common to use three small tufts of a special yarn. These are added in three different colours - so that they are more likely to contrast with whatever light or background they are fished against. Typically, the three colours will include a lime green/chartreuse (or yellow), a pink (or red) and an orange. This yarn has a very special construction - because it is made from bundles of very thin fibres which have an incredible amount of "crinkle" to them. This means that, when you stretch them under tension, it makes a very narrow floss on a spool. However, when you tie them on to your tippet - and trim the tag ends - the fibres fluff out. In this way, you can create quite a large outline - but with very little additional weight. These incredibly visible, but incredibly light-weight, sighters can help to solve difficult light conditions and really help you show up even delicate bites when fishing with nymphs or wet flies. It is important to set the hook at any unusual movement - and if you only ever rely on feeling for fish; you will miss the majority of chances when nymphing or wet fly fishing. You can see a whole lot more on sighters in the "Spotlight on Sighters" video and illustrated chapter content that comes with The Fly Fishing Bible of Nymphing - which is available to buy via our Amazon Associates Link here: https://amzn.to/3yPuutw I hope you enjoy some extra success with the tactics in this video and those in the Nymphing Bible.
