From what I've seen myself I would say the VDZ is slightly earlier with a little more total hook and slightly less backend than the hectic I agree they are pretty close but with a slight surface change the VDZ would work as your bench mark pretty well just change the surface to around 3k and you would have plenty of separation.
The Scandal is even more aggressive than the Lock unless you speed dominate or bowling on very heavy conditions most bowlers don't see the conditions to use that kind of ball much.
The Paradox pearl is a pretty aggressive ball but more usable for most than the Scandal if you need a longer ball to switch off the lock from it would be a good choice. The biggest hole I see in your bag is that middle of the road bench mark ball and I really don't think the Scandal or the Paradox pearl fit that bill but that's just my opinion.
