Well, I don't know if your experiences would be the same, but for me, the Nemesis wasn't really the best oil ball out there, even with the surface taken down. I've thrown four of them, and all of them have needed friction on the lanes in order to make enough of a move to carry the corners.
I haven't seen you bowl in a few years, but if you're looking for something for oilier conditions that will pick up a roll sooner, then you might want to consider the Total Inferno. The jury is still out on my Fury; the sharpness at the break gives me something that I don't already have in the bag, but even in box finish, it doesn't seem to start up as quickly as the Total does.
