I think your summon is wrong, this combo needs purple shark, golden clashes with Sasukes low float to repulse chase.

Because they do different thing, Kankuro starts combo from high float, Main from knockdown.

Kankuro > Spear > Dragon > Spear > Dragon > you have no more high floats so Sasuke does 10 hit chase

Main > Hinata > Kankuro > Dragon > Spear > Dragon > Spear > Fire Ball > Hinata > 10 hit chase
