Do you have very small feet, to go with your small stature? That can make a difference in what you can use.
You might consider something like the SeaWing Novas. They're not difficult to kick, and deliver an amazing amount of power. Unlike split fins, you CAN use them for alternative kicks, and they are good stabilizers. They come with a spring type strap (which I think ALL fins should have). The big down side is that they are expensive.
Another fin that has worked well for me, with a small foot pocket for a good-sized blade, is the Dive Rite EXP. They also come with spring straps.
