CDrives need a bit of juice for the magic to work. Think the quobba fins may be a better choice in the small stuff.
In my experience the C-Drive provides ton of grip, even at very low speed, but they still manage to be easy to handle in the juice and at high speed. For instance I had keels in a mini-Simmons 6'10" SUP, and they were great in small waves, but as soon as the wave hollowed, I didn't have enough strength to control the board. By switching to C-Drive twins, I had nearly as hold as keels on small waves, but the board was much more nimble in hollow waves.
C-Drive are especially great for people going down in SUP board sizes, as their extra grip at low speed will help mastering the row, especially on takeoff.
Quobba are different, for them to shine you need to go fast. They can work in small or big waves, as long as you go fast. Otherwise they are not very different from standard fins. So unlike C-Drive, you may have to change your surfing style to benefit from them.
