either or is fine to be honest. i run dual taper, but the tapers were fine too. also u might wanna pick up metric bits below if you dont have a 1.2 or 1.3mm drill bit. 1.3x4 front and rear is a common piston size used by people at my track and in many of the setups posted. you will wanna hand drill those 1mm holes out with the bit of your choice.
