The hopper/dropper combo, takes same principles but applies them to a dry fly. Using a larger dry fly with lots of buoyancy, and gooped up with Gink, you then attach sub-surface dropper pattern that will have you fishing sub-surface as well. If you are using a buoyant enough dry fly, then you may even use a small split shot above your sub-surface pattern, to help it stay down.

Rigging Dropper

There are fancy ways to attach dropper flies to your tippet, some use tag ends of tippet, to attach dropper fly, others use loops on tippet itself. But for me there are two very simple ways to rig dropper. After you have tied on your fly at end of tippet, you can easily attach about two feet of tippet through eye of that fly, and then attach another fly and other end of this tippet. This method does not work well if you are planning on attaching a split shot above second fly. The other method involves rigging up normally, and then at end of bend of fly already tied in, tie in a two foot or so section of tippet, and then tie in your fly at end of this section. The drawback of this method is, it is easier to lose your dropper fly, especially when using barbless hooks.

Cast these riggings with care, as it is easier to tangle your flies. Once tangled it is often easier to cut rigging off and redo it, rather than try to untangle two flies. Also cast very tightly, as it can become unwieldy with wild casting or under windy conditions. The last warning is in regards to releasing fish, always make sure both hooks are out of harms way, before releasing your fish. It is very easy during release to snag fish, your hands or your legs/waders, with free hook.

Dropper riggings are great for searching for fish, they take a little practice to cast and to tie. But rewards will quickly outweigh time invested to learn proper way to do it.

Since current is stronger near surface, you should also try to dive as deep into water as possible. You should try to go to bottom and use your arms as a help for pushing your body and moving on easier. While being at bottom, you should also take advantage of natural features such as crevices or bottom gaps if you wish to take a second to rest or to evaluate your environment.
