Brickguy, based on what you have said, and also based on my experience on all of the afforementioned balls, I would say your best bet is to go with a Tsunami for the synthetic house, and the Dirty Bomb on wood.
Wood lanes in my experience tend to smooth out reaction shapes compared to synthetics, and the Dirty Bomb does have a little more punch than the Uranium Pearl, so I think you would be happy with that choice.
My Dirty Bomb is drilled stacked (but very slightly CG out), all of my other stuff is label. I have used my Dirty Bomb on both wood and synthetics and it is definitely more predictable on wood.
The Tsunami smoothly covers about the same boards as my Dirty Bomb, and much more predictably. I love it especially when the transitions are taking place, because it lets you continue to throw the original line during the transition without paying full price in terms of ugly leaves. It gives a great read of how the lanes are affecting your reaction. I can't think of a better ball I have ever seen for touchy lanes.
And yes, I would classify the Tsunami as a true benchmark ball, versatile on a variety of conditions. Dirty Bomb, not so much, but wood helps with that problem. I haven't tried it yet, but hell, I'd bet the Tsunami would cover you in either case!
