This summer I got a chance to try (and bought) a set of turtle fins which are awesome and work very well for me.
Last week we went to HI and since the turtles don't fit without a boot on I had to take my Vipers with me. Even in the warm water with less gear on I still had a lot of flex in them. I did not feel like my finning was as efficient as in my turtle fins.
So my question is what do other people do when they dive in warm water? From what I was reading it looks like all the turtle fins are built big for boots. Is there another brand of "stiff" fin out there that fits well in soft boots?
Here is a pic showing some of the bend. it is not uncommon for it to be bent 90* in some of the videos I have.
