Z were (are..) a precision hand laid carbon foil and very durable structurally, but surface condition of all fins like Z is important, take good care of them and you will get the best performance and a long service life ( as long as you keep them away from hungry rocks

Thanks, I do have the fins in my possesion and I kept them in perfect condition with their covers.
So the 40cm wont be a perfect match for the 7.6 what about a 44cm? will be better you think?
Thanks for your honest responce.
