What about getting a Topre? Note that I've never tried one, just Browns, though I intend to. From what I've gathered, Topres are more tactile and less noisy. I'm honestly not happy with the Browns, I end up typing slow and gently or using ear plugs. When I type at my fastest, Browns are quite noisy even though I don't bottom out much, because of the keycap rattle and "top-out" noise. Blues are obviously out of the question if you want quiet.
Also, what is the the rationalization for making the tactility of the Browns so subtle, really? Clearly you're not supposed to bottom out (at least on plate mounted boards). Is it just a silly design?
