Short, stocky, horizontal growth, as many of the branches on your 'African Pride' are, are better suited for fruiting than the long whips on your 'Lisa.'
Now that it is this late in the season, you might as well wait till February to prune the 'Lisa.'
Next season, when a branch gets about 4 feet long, cut about a foot off the tip, leave a couple of leaves near your cut, then remove one leaf off either side part way down the branch. In less than a month there should be new side branches with new flowers.
