IIRC, isn't the first half relatively smooth until the carousel? So maybe he could stay in full stiff. Personally, I'd just stay in one setting. That last thing you need on the 'ring is one more thing to think about.
Some body roll isn't bad as long as your suspension doesn't bind or run out of travel. Which can be an issue in the rear with the separate spring and damper. Your travel will be limited by the spring most likely.
