One last thing, as everybody must be weary of my successive posts:
Like Mike said, imagine a foe is actually before you in these solo routines. For example, such is really helpful, if say, you are doing a drill or flourish or whatever based upon the Vier Versetzen. Do so with a scene playing out before your eyes as if the foe were in each of the main Huter/Leger that the various Oberhauen of the V-V mean to counter in Vor or Indes; and accordingly do those Oberhauen to strike him. In fact, doing a tour of the V-V is one of the best things you can do in solo-work, I think.
