Every piece of tech has a use and a time to use it. Obviously when a window of opportunity comes to just throw the hell out of somebody, you may as well use the right tool for the occasion.
One of the pieces of tech involves a string that ends with a high that not only stuns and catches crouches and low holds, but is not a natural combo and can be blocked, leaving Akira at +6. But because of the constant counter mashing (especially low) I'm more inclined to just wait and grab and not even bother.
