What is xs2?

What is xs2?  

Small diameter "fast flight".  Brownell's site only lists it as "100% HMPE", which leaves a lot to question.  Might be Dyneema, might not.  Might be SK75 or SK78.  

8190 is the strongest and most durable 100% HMPE material on the market.  It's SK90 Dyneema.  BCY has the exclusive rights to it in string material.
