I'm also a mixed opinion. Casting to cover or structure, or a given location that is showing fish, I'll take a straight tail. BGBS and Assassins(Stingers) during different conditions. Trolling I prefer something with motion, such as a curly or paddle, that also creates vibration. If trolling with a spinner blade(Roadrunner or Beetle Spin) the motion tails are an option, not a necessity. Casting with a Beetle spin I prefer a curly to help it stay shallower at a slower speed. Slow usually produces more for me.
