Thank you all for the responses. Actually, there were many more responses in the thread (T-GOD, Doug Sterner, etc.), but they disappeared. Anyway, I appreciated the input.

After thinking about it further and looking at where I have holes in my existing lineup, I decided to go with the Uranium Solid. The original looks interesting, but would overlap too much of what I currently have. I know the solid is more aggressive than the original, but I only have one aggressive reactive currently at my disposal (most of my oil balls are particle). The Uranium solid probably won't overlap what I currently have.

The ball showed up at the shop yesterday, and I'll be throwing it for the first time later this afternoon. The cover is really nice looking, but I was surprised at how dull the ball is in box condition. However, it looks tuneable.

I'll report back soon.
