I use the 2180 in combination with a Gitzo carbon tripod (GT2341) for my Nikon EDIIIA (60mm). I find the head quite nice. It's fairly smooth with no significant backlash, and most importantly, it's really quite light in weight. However, it's in several ways a compromise - it *does* vibrate somewhat in the wind and even though it's quite smooth, it isn't as smooth as some other (heavier) heads.
Anyhow, even after some pretty extensive use I'm happy with that combination.
