Amazingly enough, my Inv/SS tank does NOT have/use Rage.
Indeed, I have a very limited set of selections from SS - Jab, Haymaker, Taunt, Knockout Blow and Footstomp. I flesh out the attack Chain with Air Superiority, which I consider the superior pre-requisite for flight, and also have hasten.
Why did I not take the other powers?
Punch - I consider it an underperforming power, and would much rather my second defense pick instead.
Hand Clap - I want to keep my enemies close to me - not knock them away where they might stagger out of my aggro range and attack the rest of my team.
Rage - I've never seen the need, and frankly, I'd rather not have the crash - I put up with it crashing enough when I have to use unstoppable, and I'd not like another - smaller - crash from Rage.
Hurl - again, I want to keep my enemies close - but the animation time on this power is a bit long and slow, so I skip it.
This means I have 5 of my secondary set and all 9 of my Primary set. Add in 3 powers from the Fitness Pool, 2 from the Flight Pool, 1 from Speed pool - leaves me with 4 slots for an ancillary Power Pool - though one one respec I took only three, and added super-speed for a dual movement power build.
