The opening poster asked a good question, so lets stay on topic
You can practice your break also by racking just three balls in a triangle on the spot, and breaking in conventional manner -- very light clip of the head ball and then into the second ball, which if hit perfect should send the third ball close to your pocket. If you are getting good results with just the three balls, then rack them all and repeat...
Practice your banks too. work on your speed and accuracy, and of course, avoiding kisses.
Bill Stroud's practice of pocketing a ball and trying to run the cue ball into a second ball could work with banks too. In other words, doing that practice you could put the second object ball somewhere where it could either represent a ball or cluster that you wanted to bump the cue ball into, or a position ball that you wanted to fall behind to continue your run, or maybe you wanted to get tight behind for a safety.
