Matching Ying Yang ProYos II ? I knew they were lying around somewhere.
And also a modded ProYo II - Bumble Bee bearing and spacers with cut down original wooden axle. I cannot for the life of me recall the name (something vaguely Japanese perhaps ?) for this. It works, for a given value of “works”.
As requested, the Doctor Popular Super Scientist and the “carbon fibre” Dark Magic (it’s dipped as far as I can make out). Both bear the scars and cracks of Yoyojam’s plastic choice. Neither have fallen apart. Yet.
