Let’s look at combinations 8 and 9

Because they are so similar, we chose to look at combinations 8 and 9 as a group. Combination 8 required some adjustment, but I agree with Tom Cambell’s take. Putting the foot down between the kicks allows much faster movement. Combination 9 shares the flaws and strengths of 8 as it constitutes the first two thirds of the technique. We explored a couple of options, and offered a few viable choices. I even brought in a variation from Kempo-Jutsu. Given that 8 is really a subset of 9, do we really need both?
