Troutline Pale Olive CDC Dun Dry Fly BL is used early in the morning or late in the day. This model has a subtle light olive and tied on small hooks like #16 and 18 is absolutely deadly.When the water level is high and trout is hunting close to the river bank, then a size #14 will work great. We recommend this type of fly in Summer evenings and we consider a must have fly for trout and grayling!
