Hi, your problem is not the fins, it is the board length.
Paddling a 6'1" is totally different than a 7'11", you will have to learn a new technique, and practice on flatwater.

- Try to use the biggest fins possible (twin fins, keels) for the first sessions and flat water practice. But this is not mandatory, practicing sprints as if you were catching a wave on flat water is the best way to progress.
- Controlling the angle (rocking) of the board with your weight becomes very important on short boards.
- Avoid chop, which makes things insanely hard to learn this technique
- Then, I would recommend the C-drive fins as they have huge grip at paddling speed while not tracking at surfing speed.
- Once you have mastered the technique (it will probably take months), you can switch to Quobbas.
