Modding Zaul

So I've looked at the guides, looked on CrouchingRancor, and can't reconcile how I'm going to mod him. Looking for advice really - for what it's worth, he is going to lead a mainly Sith-based team and my focus is to be competitive in the arena. I have a speed set I could bung on him, but I'm thinking that with his low base speed, this isn't going to be too much use.

Input very much welcome - and thanks in advance!

Just adding that I also searched for (and read) other posts on the topic of modding Maul / Zaul, but I feel it's relevant to ask again with the inclusion of Nihilus and the buffs / changes to Sith in general.
