The Klink & Dink fly provides a super easy and secure way to attach a dropper to the hook of the fly. This allows you to suspend a small nymph or buzzer underneath. Fishing like this is often referred to as "New Zealand Style"
The fish will either rise to the Klinkhammer or take the nymph underneath making the Klinkhammer disappear. For my river fishing, I like to fish this method with a simple hares ear or pheasant tail on the dropper. On still waters, I have found this a deadly method when the fish are sipping at midges, especially on those difficult still days. For this, I have a couple of favourite buzzers I like to use.
