If you mean trout, these cover the most common trout situations: technical surface feeding and subsurface searching. The three Harrop dry flies are best when trout are rising to specific mayflies—Trico, BWO, or PMD—and need a natural drift. The Mini Articulated Trout Slider - Fulling Mill is a strong streamer choice for active trout in moving water, especially if you want a smaller baitfish-style fly. The Micro Pat's Rubber Legs is a good bottom-oriented nymph when trout are feeding deeper or want a smaller stonefly profile.
Switch from dries to subsurface flies when trout stop rising, the hatch thins out, or you need to cover water faster. Move from the streamer to the nymph when fish are holding low, the water is clear and pressured, or you’re not getting follows on top. If trout are feeding on larger prey or in stained water, the streamer is usually the better call.
