Great post! We were originally not going to do a Black pen - but I just love, love, love that green sheen on them! Blacks from a BBS pen just don't have that same glossy look IMO. However I would never hesitate to buy a black which came from a BBS pen.Such a good answer to this Question. There is nothing like a beautiful very dark black with the green sheen! Im not afraid of black from BBS.. they are genetically Black not dark blue and some of them very nice and dark but breeding back to a nice black from generations of black breeding is great if you can. If not just keep breeding the best black you have to the best black. I love, love , love blacks I am loving the beautiful green in this boys feathers right now. I can wait for him to grow up!
