I've never thrown the BW, but I had a Big Deal that I used for over a year and it was one of my favorites, the most versatile, predictable bowling ball I've ever thrown. The coverstock is very, very durable and configurable.
That BW should be more angular than the Big Deal, which is what everyone seems to be looking for, but in my experience, the Big Deal was very predictable to the breakpoint and kept plenty of energy at the pins, which should count for something.
Either way I don't think you can go wrong, although the Ebonite Total NV seems to be hot new ball comparable to the BW, but maybe a little more advanced.
