I'll have to give this keyboard a little more time, then, and hope that it starts to feel a little different. It's funny that I originally swapped out the silent blacks in my G80 with browns, and felt like I made the wrong choice, so I switched them back. I feel completely the opposite about this Das Keyboard, that maybe silent blacks weren't the right choice for it and I should have stayed with the original browns.
What springs are you using that have a 58.5g weight? I assume they feel just a tiny bit lighter than the stock springs?
