11. What Hook Size Is Best For Tying Or Buying A Copper John Fly?
The best hook size for tying or buying a Copper John fly depends on the size of the natural insects you are trying to imitate, as well as the water conditions and the size of the fish you are targeting. Generally, Copper John flies are tied on hook sizes ranging from #12 to #18, but smaller or larger sizes may be appropriate in certain situations.
- #12-#14: These larger hook sizes are suitable for imitating larger nymphs, such as stoneflies or larger mayflies, and are often used in fast-moving or deeper water where a larger fly is needed to attract attention.
- #16-#18: These smaller hook sizes are ideal for imitating smaller nymphs, such as midges or smaller mayflies, and are often used in clear, slow-moving water where fish are more selective.
- Water Conditions: In fast-moving or murky water, larger hook sizes may be more effective as they are easier for fish to see. In clear, slow-moving water, smaller hook sizes may be necessary to avoid spooking fish.
- Target Fish Size: If you are targeting larger fish, such as trophy trout, you may want to use larger hook sizes to ensure a solid hookset. If you are targeting smaller fish, smaller hook sizes may be more appropriate.
- Matching the Hatch: Pay attention to the size of the natural insects in the water and choose a hook size that closely matches their size. This will increase the chances of fish mistaking the fly for a natural food source.
