You should try them because they do something no other bass spinnerbait blades do well. The double Royal blade configuration (when spaced properly) almost constantly keeps both blades turning. Even just with a tight line glide so the bait slowly descends and pendulum falls forward toward you on a tight line or super slow-rolling retrieve. When you kill the spinnerbait and just let it deadfall, both Royal blades rotate on the fall better than any other blade pair combination. Especially the front blade stalls on many other blade types. When the retrieve is paused, stopped or too slow, most any other front blade stalls or stops, and on a very slow roll, the back blade can stall or stop too. But not the Royal blade. The Royal blade pair hardly ever stops turning, no matter how slow you go or on a deadfall, and that's the reason you should use it.
