If you're doing 63k DPS then I assuming your gear level is low. Most people agree as a rule that you want to stack haste until you start getting energy capped. For example, if you find yourself unable to use FoF or Energizing Brew without capping energy then you should start dropping haste.
Once you get to the point that you start energy capping, then the weighting between crit and haste is debatable. For example, do you only energy cap after double mastery procs? Are you only energy capping half the time during Energizing Brew? There's a big difference between energy capping constantly vs. energy capping intermittently.
