Uuuummm, Vaapad form was invented by Mace Windu who has yet to be born... At this time period the style would have Juyo which is similar as it is the style to Vaapad but the Jedi council limited it's use as it can lead to the dark side as such very few Jedi practice it however many Sith use Juyo with no hesitation as it is about power and focus on using the blade to rip apart your enemy.
