From what I've seen, the Wrecker isn't what you would think of as a "weak" ball. On a house shot, you would probably get away with being able to use it all night, and see more ball motion than your heavy oil stuff, because it's saving energy. Now, without being able to see you bowl (A video would really help us with a lot of your questions), it's just shooting in the dark.
Personally, I drill all of my stuff with 2 drill patterns. I barely want to bring my heavy oil stuff anymore, because my lower end stuff (900 Global Hook series) work so well, and I don't have to make major moves all night.
