I experimented in tag dedicating my whole day to my team and I want to say that Tina's best juggle continue-ers are
9pk
6pp6(held)k
4pp
The last two are significant being that they can be used against the wall, which is something to consider.
And maybe some odd ones, but not recommended or to be used unless you find a use for them, but I was literally trying liek every move she had and I they kinda worked, but like I said not recommended cuz the 3 options up there are better.
66ppp if it's super high/if you have the air time
and maybe just 9k
