to be honest I don't like jetfins. I tried the XL and they didn't fit, and the XXL were like canoes. I am the sort of person who does not like making DIY alterations, so being able to make the foot pockets bigger is not for me.
On my DIR-F I tried and liked the turtles, and being big doesn't bother me as I am not exactly small, and they look ok on my canal barge sized feet.
