Seems like a good idea. That's actually what Jed Davis did before writing his now famous "Spinner Fishing for Steehead, Salmon, and Trout" book. His approach was very scientific by noting date, place, air temp, water temp, weather phenomenon like fog, drizzle, or full sun, gear / lure descriptions, water clarity, etc.
Case in point: right after devouring Jed's original book, in the mid 80's, I made some all black spinners. Black clevis, black blade, black beads, even black tubing over the hook shank. Then proceeded to hook into 4 big and fiesty Fall Nooks, in matter of a hour or two, at Moonshine Park on the Siletz. Peeps still think I'm crazy for using all black spinners. But in the right conditions in the Fall...BAM!!!
