A motivated advice will do better.
First of all, what is your weight? If your weight is under appry ox. 80kg I would never buy a 14m2 R7 unless you have poor conditions at your local spot. But you do already own a 9m2
I own a 12m2 R7, which brings me upwind starting at 11kn (measured). The bigger R7 are for heavy weight riders only. The wing is so efficient, you really do not need a bigger one. I even know guys of my weight who do not go bigger as 10 or even 9m2 as their smallest kite (approx. 75kg and less)
TorchIII 14m2 is a C-shaped hybrid with good high-end, but the low-end is not compatible with a R7 14m2. I would say 12m2 instead.
From my own experience the TorchIII is also a jumping machine, where I find my R7 more difficult to jump. Compared with the 12m2 TIII the R12m2 jumps as high, but with more hangtime. Since a 14m2 TorchIII is a big kite I doubt if it is fast enough for big air.
So compare TorchIII 14m2 with R7 12m2, I am sure the last one will jump higher. By the way I have a quiver of R7 12m2/Rebel7 9m2. I do not see the big overlap as a negative thing. I am even thinking of switching the 9 for a R7 7m2 or Rebel8 7m2 (claimed to have more power than previous model)
