Here's the mod pics I promised...
I just took off about 14-15cm (5.5 inches) of the top rails with a razor blade. This alleviated some of the stiffness in the down/front stroke.
I read that someone had ground/filed down the plastic ridges on the bottom, but I didn't want to weaken the fin on both strokes.
To me, this modification has increased the efficiency of these fins for surface swimming with minimal loss on deep power coming up.
Let me know if anyone needs more of an explanation.
