Stick with BB till you know it inside out. Once you can hit a fantastic percent of winning trades with only the one Indior, I suspect it may be worth trying another. In case you've got enough time, demo with the 2nd indior till you get at least the same win and then see which of the 2 seems simpler. Attempt them together for a little while, this might include verifiion to keep you out of some losers.
However, the clearer your display the easier it is to concentrate on price. Study this thread if you have not seen it yet, and combine the Price Action with BB first.
