I use the head with the 055PROB and am thrilled. I've been 4 years with the combined road and have never had any problems. Everything can be set fix and determine. The quick release mechanism works only really good and the processing is correct.
Ledegem at very heavy lenses (eg Canon 100-400 L) it is with the vertical settings a little bit fummeliger. Once you have the hang of how far the head is nachsetzt in the vertical but not an issue.
