First one, then t'other.

If you're not rapidly switching back and forth, are you even fidgeting?

I once saw a replica of a Naruto Shuriken as a fidget spinner. I really want to find one, but they all seem to be from sketchy looking websites lol

Why not both?

Fwy would simply fidget the spinner whichever way the spinner wanted to spin.

Spin the spinner both ways, one way once and another way later even.

I usually spin counter ish, but it flips if you rotate it.
