C-Drive provide lots of grip at low speed, which can be handy on hairy take offs and angling early on fast waves where you do not have time to commit to a proper bottom turn. But they shed extra pressure so you do not "foil" (have the fin try to turn over the board) at high speed like other solutions to have grip at low speed like large fins or keels. And they are tolerant to mistakes, if you do not set up properly the rail in turns they can prevent a spinout. You can push super hard on your first bottom turn for maximum squirt (drive) without spinning out, even if you do not have yet built your full speed.

For the sizing, you can use the same scale as other fins: use medium C-Drives if you use medium AMs.

Quobba on the other hand are "just" better fins: they provide less drag and more hold. But you have to adapt your trajectories to take advantage of the added speed, for instance you can get higher in top turns without getting stuck, take a higher line in steep walls that was possible with normal fins because you can actually transform the added push into a faster speed, etc...

So I guess it could be summarized as: are you thinking:
- "I would like to push harder in my turns but I am afraid to spin out" -> C-Drive
- "I would like a faster board to complete my turns, throw spray and make fast sections" -> Quobba

As a personal note, I was hooked on C-Drives while my boards had FCS1 boxes. But with FCSII, the advantages vs AMs were not big enough to offset the convenience of the FCSII tool-less system - and I have no issue with the row effect anymore -, so I never used C-Drives anymore since my boards went FCSII. But with the Quobba, no question, they are so worth it...

Thanks Colas, interesting feedback. You're definitely on the quobba vibe now I see!

ill try ask this slightly differently: what do you think I'd gain over my am's by going to the c drives?

I guess with the supertech, I like the board but would like it to turn a bit tighter but still while being able to hold a high line on a hollow-ish wave and have more speed (?) than a thruster?

i guess I love the feeling of me EA fibreglass quads (fast, can hold a high line and also semi-loose), but with the pivot of a good thruster set.

ive also never tried a twin for a comparison, not sure if that would work on my supertech?

For me, it means Quobba. I don't think C-Drives help in tightening turns, the added drive on the opposite may widen them, and Quobba are the solution for the need for speed.
C-Drives or Quobba will both help holding high lines, but with the Quobba I can "escape" more easily if I get too high, as just angling a bit downwards will provide the extra speed that can make the difference between escaping and getting stuck.

C-Drives are great however to survive when the foam hits your board, for instance if the ball of foam catches up up with you in the pocket, or in the rebound at the end of a cutback. Or generating speed by pumping in weak waves.

Another comparison would be that C-Drive have the low end torque of a muscle car, quobba the top speed of a race car.

After 18 months on the Quobba, I can really say that all the testimonials on quobbafins.com/testimonials/ sound really genuine.

This is making it really tough! I hadn't even really looked at quobbas after all the hype of c drives!

Make it easy .... go both
Colas really has described the merits of both to the conditions
Different days , different waves , different fins

And if you are not with FCSII boxes, hence have not to balance the benefits of these fins versus the practicality of a tool-less FCSII fin, there should be no hesitation: Go either C-Drive or Quobba... or both! You wont use traditional fins ever again.

Plus your money will go to real surfers and craftmen, not shareholders of Private Equity firms.

Apologies for the confusion with the Twins production run, I had earlier reserved fins with Troy when he had a small Twins batch going to him.
Thought it was a test batch, not so , Troy 's made them before and this is the profile...

Not sure if you had my twins from before but they're slightly bigger than that ( a lot bigger than my XL or Larger thrusters ) - or slightly bigger than a MR size Twins. The Trailer is half the size of your Grom size fin it's my smallest fin similar in size to the MR trailer.

Hopefully this will help folks with sizing queries....

Yes benji go both Quobba and Cdrive, that is what I do - Quobba when it is clean and juicy and then Cdrive for everything else, and maybe mix them together Quobba front and Cdrive back or Cdrive front and Quobba back (experiment with them) it has worked with other fins for me, and if you really do not like the fins then they are really easy to sell!:-)
