Definitely the bottom rig Parker.

The pro's know how to get each spoon spinning in a different direction, otherwise known as the "death spiral." It is a 100% rig for sure.

As for the stickers, opposite and opposing for maximum visibility.

But, I must say, double stacking is sooooo last year. Triple stacks only for me. Bigger is definitely better. I am working on a new Y formation that I think will be the ultimate. The flying V is another concept in the works.
