Brown is just so common (or old school) among geekhackers that all they would talk about are those less common ones, i.e. cherry red & topre
Meh, I have tried browns, and on paper it was what I was looking for - a tactile but reasonably quiet switch. The problem is, both regular clears and ergo clears kick browns' ass.
That said, my initial exposure to browns was on used POS boards - after going through that phase and settling on what I really liked, I bought a Noppoo Choc Pro barely used and those browns actually feel pretty good. However, that board is not in regular rotation because I've been switching back and forth between blues and a Model M.
Maybe I should drag the Noppoo out again and give it an honest try. I just feel like the springs are too light and the tactility not pronounced enough for typing. The click of the blues does annoy me a little bit though, because I know that unlike buckling springs, it's artificially generated, and I really don't need the audible feedback.
Of course, that whole line of reasoning makes me want to buy some brand new clears and remod my Filco, this time with new stems and springs rather than ones harvested from a used POS board. Because, if brand new browns feel almost as good as ergos made with used stems, then what would brand new clear stems feel like? Of course, down this path lies madness. (and eventual bankruptcy.)
Edit: this whole train of thought made me drag out the Noppoo. I really like the feel of the keycaps on this thing. It's a shame they didn't do a better job with the font on the keycaps; that and the gamer-goofy logo are my two main complaints about this board. Other than that, it's really a nice piece. I love the Cherry-profile keycaps compared to the higher profile that everyone else uses. But like everyone else, no clears (sob)
Edit2: I see what others have complained about re: sliders feeling frictiony on browns. I have a well used POS board that I put back together to sell (someone please buy it!) and since I had the sliders out to try ergo clears, I lubed them - the switches on that one feel much smoother than the nearly-new ones on the Noppoo. I hope the Noppoo ones break in... otherwise I'll have to try to lube this board, and that sounds like a pain in the butt.
