Arista Legacy Pro 100? Acros? Neopan SS?

Is Freestyle's arista legacy pro 100 Acros or Fuji Neopan SS?

I would be interested in it if it is Acros but not if it is the old technology Neopan SS which historically has not been available in the US.

Also is Arista Premium 400 definitely Tri-X?

It is Acros and the other is Tri-X. Happy shooting!
