That sounds pretty good, but I'd personally add something that is a tad weaker. A Rampage with a longer pin to pap sounds like it would fit in nicely with the stuff that you already have. I really don't think that they have anything like the purple thunderstruck, meaning something that is suited for lower volumes of oil, but is smooth rolling. The reason that I mention that is because everything that you have already is smooth rolling, even the fury pearl should be fairly even with the symmetrical core design. The closest thing that I can think of would probably be the red pin zone classic, but even that is a pearl.
