Hey Hey Hey, that was when I was using my blues with no o-rings. I have greens now...
but as zero has said, find out what kind of switch you like the best and then go find a keyboard. I personally cannot recommend Ducky keyboards, because for me I have had way to many problems with the LEDs just randomly dying on me.
As for using the snow ball, just put it as close as you can to your mouth and mostly it will not pick up the sounds of the keyboard. But it will be picked up if you're in a skype call. Teamspeak is lot more forgivable since you can adjust the sensitivity.
