The chart above may need some explanation. Yo-yo string is a basically a "loop" of string. It's made up of different parts: the doubled part of the "loop," the segments that the string named for (Type 6, Type 8, etc.), the strands that make up the segments, and the fiber that makes up these strands. With this in mind I hope the chart is a bit easier to understand.

I suppose most surprising was the extra thick extra long horrible stuff (everyone this stuff at one point); it turned out to be, by definition, a Type 6 string. The Bee string was identical to the other colored type 6 string. The Proyo Type 10 may be the most confusing name, by definition it should be a type 8 (much the way Slick 6 is a type 6). The Albion seems to be truly a Type 10, but you can see it skips the "strand" and goes right to fibre at that point. This may explain why the Albion string feels so soft.
