TRoad Pearl is a good choice, I have one and it controls the wet/dry better than the others you mentioned. I've tried alot of the storm balls with the Reactor cover (Fired UP, Spit Fire, TStruck Pearl, Domination and Agent)and I've had some trouble with over/under with each one of them on a house shot. In the 2+ years I've been bowling again, the T Road Pearl is the best ball I've thrown and I've tried many. I'm thinking of drilling up a second one to complement the one I currently own. My T-Road is drilled with what I call the "Hand Friendly" drill which places the mass bias under my thumb and the pin 4 to 4.5" from my PAP. As long as you can find a little head oil somewhere, you'll be fine but with this drill if the heads are fried and loft doesn't work, put it away. I'm sure with a 5.5" to 6" drill, it would push through drier heads better, which is why I'm thinking of drilling a second one.
