How to fish it · for Rainbow
When
April–June
Where
Start with Minkie (6-10) — on the point. Rainbows respond to more active retrieves — try short strips between pauses. If that does not produce, switch depth or speed before changing the pattern entirely.
The plan
Plan A
Start with Minkie (6-10) — on the point. Rainbows respond to more active retrieves — try short strips between pauses. If that does not produce, switch depth or speed before changing the pattern entirely.
Plan B
If the main plan stalls, drop to a size 14–16 midge — switch to a washing-line or suspender rig and change drift line before you change food group.
Watch for
Watch for Sedge towards evening — this could be the best window of the day.
Bank
Bank-only venue. Fish from accessible margins, points, weed edges, and inflows.
