I have a solid fury and it is a very strong ball, especially when in its out-of-box finish. It will handle heavy amounts of oil, but is very versatile and surface changes are pretty easy without making the ball real finicky. I have mine highly polished and it is a lot more skid/snap than before, but will still read the heavier side of our house conditions with EASE. I think I could even use it on a much heavier condition, even with the polish.
If you are wanting to try a particle, I have to agree with the sidewinder for that. I don't personally own one, but a guy I bowl with does. The ball clears the heads cleaner than I thought it would, picks up the lane well in the mids with a really good transition phase, and never quits on him in the backends. Good control with power to get those corners out.
The knock that I have heard on the Rampage is that it is a bit too oil sensitive and that carry down affects it quite a bit.
