Hello from Italy,
buy them and you will never regret it. I just got mine a couple of weeks ago directly from the factory (20 km. to my house), and they are really revolutionary and fantastic. They are completely (and pleasantly) different from all the other fins I have (both plastic, fibreglass-carbon and pure carbon). Almost no effort and not ANY kind of fatigue and pain even after prolonged and powerful use. After reading the very few reviews I could find about them, I was not sure between the 25 and the 30 spearfishing (1,86 mt. and 85 Kg.) but at the end I went for the 30 and I am happy I’ve done it. Effort required is so low I would recommend the 30 to everybody, except maybe (maybe, neither sure about this) to people that suffered serious injuries in the legs. They require less effort than the softer fins I have, but they deliver a power comparable or superior to the longest and stiffest I have without being tiring, bulky, heavy and exagerately long so giving much more agility. I was trying them firstly in a swimming pool, trying to stay behind a guy with a physical structure similar to mine, he was wearing Cressi Gara 2000 HF, the stiff ones. We have done about 30 pools in a row, swimming fast, and I could easily, without effort stay behind him almost attached to his fins all the time. Nothing special you say? He was swimming legs and arms, me only legs! Had all the eyes in the swimming pool on me (and I’m not a champion, you can bet on it!).
The foot pocket is really a piece of art, so comfortable and transmitting all of the power to the blade, but you have to take at least a size bigger or more than normal as it’s quite short fitting. This is really something you should have to try before to buy.
About how they look like, it’s of course a matter of taste, but I really like them. What I can say, for some strange reasons, they look much much better and “proportioned” in reality than on pictures, have no idea why.
Hope all of this could be of help.
Sorry for my poor English.
All the best from Italy, Dolcevita
