Tactical Bassin actually addressed this in one of their spinnerbait videos. If I remember correctly, he suggested playing with trailers to create more drag. I actually never even noticed baits were doing this until I saw that video. In my experience, blade size to weight can matter. My 3/8 oz baits with double 3.5 willows run flat, even when burned (thats what i built them for, burning in current). If i throw a big #5 willow on the same bait, the bait will run with a more vertical pitch. You will also experience more roll over at the same speeds. But conversely, the bigger blade provides more lift and you can keep the bait high in the water column at a slower speed.
