I tried the green on the little toe set-up and very much didn't like it. Felt a weird twist when flutter kicking and no improvement for frog.
My ankles don't bend downward particularly well so I like having more articulation that direction, also feels like less drag on the reset for the frog when I don't get the angle just right. It's possible my ideal spine would be yellow downward then somewhere between yellow and green/blue in the frog direction.
I do find that for both frog and back kick they reward longer slower cadence. For flutter it's the opposite.
