Hi Pete,
Just to let you know, i have a pair of the freedivers fins ,that I paid about R1100 with courier fees, about 2 months ago.
I dont have much experience with fins etc seen as I have only been diving for about 2 years, but so far I am very happy with the freedivers fins.
A friend I dive with has the Picasso Black Team fins and I have tried them, the Freedivers have a softer foot pocket which makes them more confortable and your feet dont get that sore that quickly, while with the Picasso the first few times you dive with them you want to cry from the pain that the stiffer pocket gives you. But other than that they are much of a muchness.
Anyway, thats just my 2c worth from my experience, good luck with trying to get a new set!
