I've got the new bio paste plus cr.ox coticule plus ch12k rasoir ti paste they all work ,i have to many option'si'm still trying work out which one i prefer, but they all work, your red dovo will be all you should need for a while. I would invest in a coticule in the future they can do every thing. Unless your rebulding bevels or repairing big chips. I use my coticule all the time followed by fine paste if needed.
