Could be the particular batch of Brown Switches too. Discussion on this was ongoing in the Mechanical Keyboard Club thread. The Quickfire TK Browns definitely have a scratchy/crunchy feel. Perhaps they do need breaking in on the order of two weeks of use. However, my Ducky Shine II needed no breaking in and the feel on it is easily better compared to the QuickFire TK. The spacebar on it is oh so rough too. Makes me cringe a bit LOL.
