As you can see from MaraJade's response they don't use it often. He's talking about in some of the eps, TOHO adds a special effects flash on some of the impacts in combat. TOHO has done this , a clear example if you have Justirisers ep 2 lying around look at the fight with Riser Glen vs the Zakoal and Cyber Knight Zaurus. Like I said, it's somewhat rare, and TOHO doesn't make a commitment to these kind of effects, so don't always expect these effects.
You know when I look at that fight of Tarious and Tawlon, it's kinda clunky at times. They get better, and make some of the fights AMAZINGLY fluid.
