Hands down, my favorite is the gray ghost with 2 or 4 strands of flash just a tease longer than the tail material. Bare lead head but have used chartreuse, Orange and black. Black head, gray body, white hackle V’s for the tail with just a few strands of flash. Variances of that as you try other material. White/gray/white w/flash. I usually use no more than 4 strands of flash but also have some without. Also, in 3 sizes at least. I start at 1/8 and go 1/16, 1/32, and 1/43 (1/32 ball head no collar, #8 hook). Many times I have the right color and have to find the right fall rate before they’ll get interested. The tiny ones get a lot of play in my boat.
Creativity is just intelligence fooling around
