I have had in my possession at one time or another … every CLYW model out there except H5xChief and Puffin. Currently I have a 2nd run Chief (meteorite edition), 28 stories avalanche and marmot, clear view station gnarwhal and Arctic Circle.
One Drop is second - I have had in my possession most One Drop models except p1, sovereign and Burnside, but right now I have - Code 1 & 2 (YYE edition), Cascade (dragon slayer edition) and a Dietz.
Other:
1 C3 DiBase
1 G2 Albatross
1 Gen-yo Torrent II
1 Gen-yo Essence
1 VsNYYC Flying Hut proto
1 VsNYYC Battosai
1 YYJ Fiesta
1 YYJ Dark Magic
1 Wooly Markmont
Looks like CLYW with YYR a close second. It’s interesting to do an inventory of all the yoyos I’ve owned. My current collection consists of an Acrophobia, E=mc^2, a Gnarwhal, and a Fiesta.
