Yeah I suspected as much Nick. I can see some of the dynamics that come into play when I overloaded my video tripod with my quarter plate camera (doesn't weight much but everything gets thrown off balance when I extend the bellows out all the way). But, I'm completely new to this and, even though I've read every post of tripod/head recommendations here, over on largeformat.info and anything else that I could get my hands on I still feel like I'm missing something ... I was in heaven when I came across a magazine review of giotto's, gitzo and berlebach tripods but reviews like that are few and far between.
I've ordered some legs and a head, I just hope I made some good choices out of the mind boggling array of options.
Thanks again everyone
