Spending another set of observation & experimentation days at DePuy's Spring Creek (www.depuyspringcreek.com), this theory and pattern of mine are gladly proven by selective trout. FA stands for "Floating & Ascending". But also it implicates an attractive FA Player who is anticipating for a lucrative "hook-up" (in our cases, trout).
Use of this fly should NOT be limited only at spring creeks. It surely works during any mayfly hatches at any big rivers as well.
