I believe Steve Brown was the first to try this concept, in the early 2000s. Here's a video (note he does catch and correct the tilt of the tops, but it gets cut off here for some reason):https://youtu.be/UbT_ufOQkVg
In this years online contest videos I saw this:would this count ? I think there are crazy 8's on both hands.
In the world contest 2022, some competitors did some trick with 2 spintop. In my opinion, one of them, 2as 2 koma player, using 2 strings is more difficult than using 1 string because when we use 1 string, it is easier to get ready for a trick.
Is there a prize?
