Which Fasttech Kayfun matches SS Nemesis Finish?

[stancato9]

I noticed there are a few on there.

Stainless Steel (A)
Stainless Steel (B)
Stainless Steel (Sandblasted)

Which one will match the stainless steel nemesis?

I also noticed it says:
Proprietary mouthpiece (NOT a 510 drip tip)

Does this mean I can't change the drip tip?
Edit: Found the adapter.

Thanks.

(B) which is clearly described as Brushed

Also the kayfun Lite
