I've always used one key (Q) instead of both (QW) and I've always thought this was a good way to go. For 1-3.5* at least.. Now that I'm moving on (or at least trying to), 4*, I've noticed that my "technique" might have some holes in it(especially when it comes to streaming..) ..Besides getting use to using both keys instead of one, any other ways I should tweak my technique?
