Those Plazma spoons look identical to what I have at home.  I  couldn't find them through Sutton when I went to replace what I lost.  Eventually I found someone selling the Sutton "flutter" spoons on E-Bay, as I recall.  They were "new" & still in a package but who knows how old they really were.

They are by far the thinnest, lightest lures in my box.

I don't give a darn what they call them.   A rose by any other name....
