I installed the non-RF version of the Continental CrossContact UHP late last summer on my X3. Good feel, predictable at-the-limit handling characteristics, fairly quite, and excellent at braking. Plus, it's designed for SUVs so that's a plus. I like it for what it is- a tire designed for performance in the summer wet and dry.

Drawbacks? German tests say it has a slightly higher rolling resistance and it rides on the firm side. Great handling, but if your roads are in poor condition, the ride won't be smooth. Don't know how much the RFT version will exacerbate it.
