you are starting to look like you're chasing your tail. why don't you just list all the tripods you are looking into all at once. then seriously look into them and find which ones are actually real similar and work from there in disposing the chaff (which there is an abundance of) from the wheat (as I commented before, not so much).
the basic reality is that for the most part many of them (due to origin) are so very similar in build to each other that the real differences are just the "look" and name (interesting as they can be).
