# **How to Choose Slotted Tungsten Beads – Size and Colour Guide for Fly Tying (Grayling Fishing)**
When it comes to fly fishing for grayling, the right materials can make all the difference. Among the most essential components in modern fly tying are **slotted tungsten beads**, which provide weight, balance, and added attraction to nymphs and wet flies. But with so many sizes and colours available, how do you choose the best one for your setup?
In this guide, we’ll break down the key factors to consider when selecting slotted tungsten beads, including **size, colour, and application**, to help you maximize your success on the water.

## **Why Choose Tungsten Beads for Grayling Fishing?**
Tungsten beads have become a staple in fly tying due to their **high density**, allowing for a smaller profile while maintaining excellent sink rates. Compared to brass or lead, tungsten beads are:
– **More compact** – Achieve the same weight with a smaller bead, keeping your fly more natural.
– **Faster sinking** – Ideal for getting nymphs down quickly in fast-moving water.
– **Durable** – Resistant to chipping and wear, ensuring long-term use.
For grayling, which often feed near the bottom in clear, cold rivers, a well-weighted nymph with a tungsten bead can be the key to consistent catches.

## **Choosing the Right Size for Your Fly**
Slotted tungsten beads come in various sizes, typically measured in millimeters (mm). The size you choose depends on:
1. **Hook Size** – Match the bead diameter to your hook for a balanced fly.
– **Small hooks (#18-#14)** – 1.5mm to 2.0mm beads
– **Medium hooks (#12-#10)** – 2.0mm to 2.5mm beads
– **Large hooks (#8 and up)** – 3.0mm to 4.0mm beads
2. **Water Conditions**
– **Fast currents/deep pools** – Larger beads (3.0mm+) help the fly sink quickly.
– **Shallow or slow water** – Smaller beads (1.5mm-2.5mm) prevent spooking fish.
3. **Fly Pattern**
– **Heavy nymphs (e.g., Perdigons, Czech nymphs)** – Use larger beads for extra weight.
– **Delicate emergers or soft-hackles** – Opt for smaller beads to maintain a natural drift.

## **Selecting the Best Colour for Grayling**
Grayling are known for their keen eyesight, making bead colour an important consideration. While natural tones often work best, experimenting with brighter colours can trigger strikes in certain conditions.
### **Top Colour Choices for Grayling:**
– **Copper/Gold** – Mimics natural insects and adds flash in low light.
– **Black/Silver** – Subtle yet effective in clear water.
– **Fluorescent (Pink, Orange, Chartreuse)** – Great for murky water or aggressive fish.
**Pro Tip:** If fishing pressured waters, try **matte-finished beads** to reduce glare and appear more natural.

## **Fly Tying Tips with Slotted Tungsten Beads**
1. **Secure the Bead Properly** – Use strong thread (e.g., 70-denier) to prevent slippage.
2. **Adjust Weight as Needed** – Stack multiple small beads for fine-tuning sink rate.
3. **Experiment with Combinations** – Mix bead colours with different dubbing or ribbing for added contrast.
