Spring or Rubber Straps?

[Shooter]

my everyday fins are Cressi Rondine. They are a stiffer fin that allow you to have excellent maneuverability.  As I stated before, I started with the split fins and they didn't have enough thrust. I was on a deep dive into some current, and couldn't keep up with the rest of the crew. I couldn't even swim against the current to make it back to the boat! I recently forgot my fins on a dive and had to use my appollo's. It really felt like I didn't have any fins on at all in comparison. Very awkward. When I go spearfishing I wear a full foot long blade fin, Omer millennium. (I would race anyone for titles in those baby's!  )they are also great for chasing fish. My next pair will be the cressi gara 3000. Also a long blade free diving full foot Fin with much softer for pockets.

I will let the ss straps go for $30
