Me thinks you are being a little over sensitive to the problem. I feel sorry that you are going have to lug that surveyor's tripod around with you. First, I would put a roll of film in the camera and determine if there is actually a problem. So far all you have proved is that it will cause water to ripple. I use my medium format equipment on a 3.5lbs carbon-fiber tripod with a load rating of 13lbs.
