Use the fin for underwater rugby. Very pleasant soft fin, which allows for untrained / damaged ligaments with no problems the entire game / training / tournaments mitzumahcne over days. In the upper speed range (sprints over longer distance) it loses against the much tougher fins, however, it is very agile and the speed saw on the pitch surface very well.
Were tested against the Stratos FP by Technisub, a much harder fin, with whom I got problems on the bands soon.
