Anderson & All,
I was thinking of same thing, mainly because I am one of those unfortunate few that equalization with head down is like 400% more difficult than horizontal. I got my eustachian tubes so stretched out now that I can equalize hand free in the horizontal position, but once I get pointing down more than 150% (180% being straight down) it all stops. I even bought an inversion machine to practice on. So far, not much improvement.
I understand the no-limit divers are going down feet first on the sled. How do their fins affect them? If I was to squeeze a rope with a weight on the bottom, with my fins & ankles, while holding on with an arm (head up), would the flow of water off the fins propel me to a side?
Hauling around the weight and rope isn’t much of problem for me, because I dive out of boat.
