So let’s look at caddis. The good old elk hair caddis has long been a favourite of mine as a dry / dropper fly, floating high with a wing angled upwards enough to see. But there’s another reason I fish them so much, trout will usually shun an emerger, dun or spinner that drags even to the slightest degree. However, caddis routinely scatter across the current and so are a good choice for tricky currents and those who struggle with drag free drifts. Whether swinging after dark or presenting a difficult drift during the day it’s always handy to have a caddis or three at hand.
