I just can't read this thread without laughing. It's one of those words that no-one can spell, another one is diarrhoea. Or is it diaroheahoroea?
Seriously, I find that it's best to start slightly positive and end up neutral. The distribution of weight is also important. Having the right position in the water makes a big difference, most of all for no-fins dynamic. If I have a buoyant suit and a heavy weight belt, my position in the water is not horizontal, with the legs and head being pulled up and the middle being pulled down by the weight. It is hard work doing even a few metres like this. This is where neckweights and ankle weights are useful.
