I got to meet up with Summer this past weekend to admire her new tail and it was so cool! It even changes colors depending on what kind of light it's in! Her fin is definitely heavier than mine, harder to fold neatly, but is also not transparent (Thanks, Jesse) to where you can see the monofin when you move the tail. It's very sturdy, very shiny, very awesome. I can't wait until my income tax comes in!
