One thing I see some loopers doing, and some 4A players, is putting holographic / optical stickers on their yo-yos so they catch the light better, like so:
And then some designs are fundamentally “optical” without being holographic or shiny, as you can see
And then speaking of the above image… my man … MY MAIN MAN … the yo-yo master who performed with Cirque … BLACK … also uses holographic stickers on his yo-yos! Check it:
You may remember that Pro-Yo II had holographic pogs which started me thinking about this:
I guess in an era of predominantly metal yo-yos, when we’ve given up “put your own circular stuff in here to decorate your yo-yo!” pog designs, it’s not cool to put shiny stickers on your yo-yos any more?
