It's supposedly a mixture of all the forms except Vapaad. Ataru uses acrobatics but Qui Gon Jinn didn't use any in the TPM and Darth Maul used a ton with Juyo. Darth Vader and Luke are stated to be the best at Djem So. Tyranus has mastered Makashi to the utmost possible. The same is said with Kenobi and Soresu. Mace being the creator can be called better than Depa.
Makashi.
I do not believe that the number one weakness in this form is that it cannot stand up to the Djem So Form - it just so happens that Skywalker used Djem So when he beat Dooku.
Using two blades supposedly does more damage but if you get hit by one of those things you are probably not getting up any time soon at any rate.
some kind of weird mix between makashi, soresu and ataru
in other words if i master it ill somehow be able to perform perfectly executed swings while jumping and flipping like crazy and at the same time incoperate a style that involves tiring the enemy out before you do 😛
but since that would be really, really hard to pull off imo, imma go with a makashi-soresu mix..
