This is a generic list. When you are starting its really about the main types of flies (streamer, nymph and dry) and their proportions. Once you get that down, it's a matter of varying color, materials (and a few techniques). If I knew more about the person -- are they going to go out and purchase high end materials and equipment right away? Have they fished for years and do they have a preference on flies? Are they going to fish certain streams or at a certain time of the year? For example if they have been fishing cane for years and love the catskills, I might go with traditional catskill dries or a royal wulff.
