I'm not sure why mrbowlingnut isn't understanding the fact that you've gotten the original Paradigm and not the Passion, but whatever. I think that there is potential for overlap, but you can probably avoid it with different drillings and coverstock prep. If you laid them out identically, the Shock and Awe would probably go a bit longer and provide more angular backend. I'm basing that off of what I've read about the Shock & Awe and how it compared to the Absolute Inferno (a ball I owned). The Paradigm should want to pick up in the mids more quickly and will be smoother on the backend. Whether or not you'd want both will depend on how many balls you want to carry. At best, I could see the Paradigm being a medium-heavy ball while the S&A could be a medium, skid-snap type of ball. So, I guess my final answer would be, yes, you could fit them both into an arsenal, but it really depends on how different you want their reactions to be.
