Help with HU skill tree for RA

[Squal_FFVIII]

This is my current HU skill tree to use as a sub for RA. As you can see I still have 7 SP left over but there isn't anything that I can give it to.

The only thing I can maybe think of is "step advance" since having some extra invulnerability for my roll could be useful in dodging?

That said would that skill even work with the RA roll? Or is that skill strictly for the "step" version and not the tactical roll?

EDIT, I meant to ask this in the "help" section of the forum and not in the general area ._.

Iron Will, probably. Give you a safety net for enemies hitting you during Sat Cannon from off screen.

Get Massive Hunter. -25% damage and you don't flinch for its duration, which is way more useful if an enemy hits you during Satellite Cannon. Also, grab Automate Halfline. Still got spare SP after that, but Iron Will won't be useful because you won't be dying.

I'd have to agree with lonelygarunga here. :D
