Well, I have the Bilstein Sports with a spring set that is supposed to "ride close to stock". So I suppose the HD set with stock springs would be similar to mine except for a higher center of gravity (a bit more roll).
I have always liked Bilsteins on every car I've had them on. They dampen small motions almost invisibly and handle larger motions with a beautiful smoothness. I've never found them too stiff for any road use - pick your spring rate and trust the Bilsteins to do a great job.
