Ive been thinking about spoons for a while, but i havnt come up with a concept that i like yet....... Im like you Brandt, i have a hard time making a lure that has been made before.. I have to change something or it isnt mine
Dave, I learn by watching.. Found some videos a while back of a guy with some sort of "test tunnel".... I looked them up again, heres one i liked, maybe it will help you on your quest

You are the fluid mechanics expert, maybe you can gather more from this than i did
What i see:
A spoon is basically the opposite of a crank bait...
- while the crank bait is a battle between buoyancy and fluid pressure, a spoon is a battle between gravity and lift
-Body WIDTH and lip angle dictate the attitude of the crank bait.. For the spoon its LENGTH and bend angle
- the frequency of a crank bait is predicted by balast and lip width, like a pendulum with weight and distance... The spoon seems eratic, but i can almost see a pattern/cycle to the action... Maybe that's where your vortex comes into play
