In my opinion Ross Macdonald's Park Shrimp is the best style of long-tailed Shrimp for slower flows. Arctic runner in the tail and wing is very soft and mobile, resulting in a fly that comes alive in water. The two head hackles blend beautifully and push water without collapsing in the current. My friend Ken Reid managed 27 salmon in a day when he used one in Russia, twitching the fly with a figure-of-eight retrieve. Once again, yellow, orange and black are a sure-fire combination but Ross has different-coloured patterns for varying conditions, including Calvin’s Shrimp, Maggie’s Shrimp, Heather Shrimp and Mairi’s Shrimp, which I’ve left until last in this list although it’s actually the first fly he designed in this style.
