## **Choosing the Right Size: 10 vs. 12**
When selecting an Olive Irish Bumble, size plays a crucial role in matching the hatch and triggering strikes. Here’s a breakdown of when to use **size 10** and **size 12**:
### **1. Size 10 – The Bigger Profile for Aggressive Fish**
– **Best for:** Fast-moving water, early season fishing, or when trout are feeding on larger prey.
– **Conditions:**
– High water levels where visibility is reduced.
– Murky or stained water where a larger silhouette helps trout locate the fly.
– When imitating bigger insects like stoneflies or small baitfish.
– **Presentation:** Fish it with a **swing-and-strip** retrieve to mimic a struggling insect or minnow.
### **2. Size 12 – The Versatile All-Rounder**
– **Best for:** Clear water, spooky trout, and more selective feeding conditions.
– **Conditions:**
– Low and slow-moving water where trout inspect flies carefully.
– Midge or small mayfly hatches where a subtle presentation is key.
– Summer and fall fishing when trout are keyed in on smaller prey.
– **Presentation:** Dead-drift it near the bottom or use a gentle **twitch-and-pause** retrieve.

## **When to Fish the Olive Irish Bumble**
This fly excels in multiple scenarios:
– **Early Season (Spring):** Trout are aggressive, and a size 10 works well in high, cold water.
– **Summer Evenings:** A size 12 is perfect for matching smaller mayfly or caddis emergers.
– **Fall Runs:** Larger trout move into rivers, making a size 10 more effective.

## **Pro Tips for Fishing the Olive Irish Bumble**
1. **Pair It with a Dropper Rig** – Use the Olive Irish Bumble as the **point fly** with a smaller nymph (e.g., Pheasant Tail) as the dropper.
2. **Vary Your Retrieve** – Experiment with slow strips, short jerks, or a dead drift to see what triggers strikes.
3. **Fish It Deep** – Add a small split shot or use a sinking line to get the fly down to feeding trout.
4. **Match the Hatch** – If you see trout rising to olive-colored insects, switch to this fly immediately.
