I bought OCCAZ (she has a year and a half) and have used it for 3 months, and frankly, it's a good start for double the price / quality ratio is relatively good, but it is not with that you reach the 230 BPMS regularly. There really is a problem between the pedal left and right and even with the settings we still have some problems (the left pedal has a lot of play, and joints not so good). With the experience I would do not have that choice I prefer 2 single with two bass drums, but if we are successful on the stuff like that, on the high end it really going alone.
