I switched from tried-and-true Seawings to Go Sports and they work very well for me. They are light, not too long, quick to accelerate, and not tiring. I've never had a cramp with them, and they are easy to pack. I'm about 50 dives in with them, including some in significant current, and have no thought of going back. My partner had big, heavy fins and also switched to Go Sports. She was a hard sell, but also is a convert.
