I know you dont like it, though; as the title says.
(I’ve got a last run Sky Walker, if that matters)
I believe it is common 100% poly.
Well i got some “candy”-stuff, yellow, orange and red. And seemed a tad thicker than the regular poly
I just got a d-bearing skywalker and it came with hamstrings.
Was it multi-tone or solid color?
Multi-color, looks like green, purple, and orange. There were 2 of them. I haven’t actually used them yet, I just threw a kitty string on it. 
Sounds like you got the same kind as me. Sure its hamstring?
Yes that is what you have, it comes with 2 hamstrings.
Thankyou!
