My spanish 11900 and TG3 BL82 have Cherry blacks that are noticably less stiff than the blacks on my older 11900 and TG3 BLT. For example I can type on the BL82 tenderly without bottoming out, and it's quite silent; I have to bear down hard on the BLT to type, bottoming out most often, making it too loud for when others are sleeping in the same room.
Has anyone else experienced older Cherry blacks being stiffer than more recently manufactured blacks? Do they get stiffer with age? This is exclusively a qualitative assessment. When I have sufficent rip-weights, I'll do a quantitative assessment.
