The Holy Grail is a great little caddis emerger pattern. The Holy Grail is one of those “go to” patterns used by many western trout guides. The Holy Grail is just plain buggy and a very forgiving pattern to fish. The Holy Grail can be dead drifted, swung at the end of a drift or even stripped behind a streamer. The Holy Grail can be tied in three main colors: Natural, Olive and Black. All are equally effective and great to have in any caddis box!
