Thank you Wotan1 for your comment - there are a couple of things to keep in mind besides use, stability and durability. Price and availability has to be considered as well.With all tripods and heads there are two main issues in addition to ease of use, stability and durability.
I am not sure any of us would be able to tell the difference in stability without running precise comparison tests. Similarly, durability requires testing over time.
I prefer to stick with the known quality brands when it comes to tripods. I prefer Gitzo, Really Right Stuff and Kirk.
I am also looking at the Gitzo (which we can get here)
I can ship some items from overseas - but it becomes a very very expensive exercise - the value of our currency is an issue.
