Not sure how many Dubia ya got, or even more important, how many adult females you have at this moment. Either way you are probably looking at around 6-8months before your Dubia are going strong so you should definitely look for something to use in the meantime. Supers work great if your dragon is big enough for em. The Turks work very well and would be breeding about twice as fast as the Dubias so they are another great alternative while you wait on the Dubias. The Turks will give you another look at a different species of roach too, so you will come to appreciate them even more in the long run, so I would vote for them personally. Really, I couldn't see why not get all three! Variety never hurts.
