The brief was a full-size organic that felt like the yoyos we kept going back to: 56 mm across, 43 wide, about 66 grams, with nearly all of its spin out in the rims. Speccy is short for spectacular, and it's the one we'd hand you first.

Undersized yoyos live in pockets and come out on walks and in queues. The trick is keeping enough weight in a smaller rim that it still spins long. It's named for the stubby, the short beer bottle that fits in one hand. This one fits in a pocket.

A servo is where you stop for petrol: in and out, no hanging about. This one is for tricks that change direction a lot, where a light yoyo keeps up and a heavy one argues.
