I'd go with the Defiant Soul. It would be a great compliment to the Critical while being a bit stronger than your Disturbed. The other thing I like about the Defiant Soul is that it is versatile on a wide range of medium-heavy patterns.
I was debating the same thing of Defiant Edge, Defiant Soul or waiting for the Totally Defiant this past week. I opted for the Critical Theory instead after finding one NIB for a great deal.
Between the Wrecker and Rumble, I would lean towards the Rumble for the time being. The Wrecker is a great ball, no doubt. However, I see this as a good time to get a solid to compliment the hybrid, which gives you more versatility in the arsenal. The Rumble will read a bit earlier and won't be as angular as the RS. It's a good step down from the Deranged you're looking to buy.
So with that, it would be:
Critical > Defiant Soul > Disturbed > Deranged > Rumble > Rising Star
