Thanks everybody.
I have changed my mind. When my board arrived a year ago, I didn't really liked the blacks, and thought browns would fit for me better.
This thought posessed me as I made this thread, but now I realized that I love blacks! ( OH I MEAN BLACK SWITCHES!!! )
Sometimes before I power on, I'm just pressing the keys randomly, enjoying my filco.
And this is - my friend - love!
(However, I started to get sick of the plastic feeling, so I decided to fabricate wooden keys for the whole board!)
PS: my english is still pretty bad
