Chineese budget ZLC blades (stuor vs huieson)

[qylw]

I have Stur ZLC blade that I like to play, so I decided to make a backup by buying Huieson ZLC, as I thought it will be identical.
I just got the Huieson, so I decided to sand the wings for penhold. To my surprise I noticed quite significant construction differences.
Posting close-ups below. (I haven't play with Huieson, so I cannot tell what's the difference!)

Both black ZLC materials are very hard to sand, so ended up using dremel.

Might be super ZLC, fibers are more dense and you can't see well the Zylon.

Super ZLC in 20$ Huieson blade?

SZLC is indeed visibly denser than normal ZLC but you can still clearly see the ZL fibers in a SZLC blade:
