Octo came up and brought his Picasso carbon blades. The Picasson system allows blades to swapped out by taking out one bolt assembly. Octo is wonderful guy and as generous as they come. He replaced my Black Team blades with his carbon blades and what a difference. On my first dive I roled into my surface dive, pulled one leg up for directional weight and gave a slow kick with my other leg. Immediately both legs were submerged and I gave a gentle full alternate kick and practically crashed my head into the -20foot platform with my ears screaming to be equalized. Unbelievable forward thrust translation. This is the only pair of carbon of blades I have ever used so I don't have any idea how they compare to other makes and models but it is like going from a good sports car to a Formula One racer. But they are expensive so I doubt I will buy any in the near future as I think that diving with my Black Teams is probably better training and I have other things that I want first; like the Suunto Mosquito dive computer, mask lights, spearguns (it is legal to spearfish from June to October in many lakes in Utah), and money to go to the Maldives.
