Maybe I can help you a little. I have designed and marketed 100’s of spinners with various blade sizes and body weights. Let’s say you are fishing a #3 French blade with a solid brass body and a siwash hook. Now have the exact same spinner with a #5 French blade and suitable body for the blade size. Assume you quarter angle a cast upstream with the #3, it will take”x’ seconds for it to drop into the fish zone by dropping your rod tip. Then repeat the process with the #5 blade. Using the same process keeping the rod tip down following the swing of the spinner, you’ll see that it takes longer for the lighter spinner to drop into the fish zone. Yes, let it make the full swing until it’s below you. I generally hesitate for just a second or two at the end of the swing. I’ve caught several fish as I hesitate at the end of the swing. This is a productive and great way to learn some basics of spin fishing for trout and steelhead. Have a great outing
