The Ales are another area of learning where the thought process involved may be of value.
The Ales came about as a result of struggling with the emphasis on footwork that so many systems use for evasion. While the basic premise seems reasonable and sound, it is very difficult to do well or fast enough. That is, that when an attack is coming, that you move your feet, which moves your body out of the way of the attack. It makes sense except that when you try it against a weapon attack, you'll quickly find that your feet are not fast enough unless you can see the attack coming. As a result, the next best thing was to find evasions that didn't require your feet to move or at least not much in order to take away the primary targets of most people's attacks. By doing so, you can perform them quite quickly which makes them much more viable for dealing with attacks when you cannot see them coming. Primarily the Ales badan come from Pamur though the context for use is slightly different and the Ales Kepala come form Raja Sterlak.
I filtered them through what I knew to work in boxing as well and thus the Ales were born.
