Which Thule foot pack for estate with rails?

As a bove really, there isn't much different in cost. I've already got thule bike carriers etc so it will be nice to get matching keys and Thule stuff is pretty good. So, which is better the standard or low profile feet? The low profile looks like it might not be as tidy when installed as it involves a band going underneath the rails. But , on the flip side it sits lower and might look more slick.
