Not too noisy, but sound feedback ? Blues have sound feedback, buckling springs also, but they are pretty loud.
The blues are really high pitched also.
Could you do with browns (light tactile feedback) ?
When you say feedback, are you talking about feedback on actuation, or when bottoming out ? Mechs tend to bottom out pretty loudly, and you really feel it. not something you have on rubber domes (mushy mushy !).
How heavy would you like your keys ? Light, medium ? heavy ? Light is under 55g, 55g is medium, above 55g is heavy.
Just dont go for a Razer BlackWidow if you dont intend in changing they caps, they are quite wobbly. Once you change them, its pretty much perfect in that sense ...
