Hello, I got a bit confused as a result of the various announcements and cancellations of new finishes for the various materials, beta groups, dye mansion etc. I think it was said earlier on that the Black Strong and Flexible would receive a new extra treatment at no extra cost (press release regarding DyeMansion). Later I see that some of the Strong and Flexible materials (orange, blue, green..) got a Polished version when you're part of beta group. But not for black ... Now there is a black premium material (2x costs), and a Black HP Strong and flexible.... These latest 2 alternatives have very differente price points and/or leadtimes. I've tested the Strong and Flexible Polished in orange and blue. These material and finish option results in absolutely gorgeous prints, with decent pricing and leadtimes. What would now be the equivalent material / option in black? Any insight is much appreciated!
