Jason,
Picture how the watts link works. They are made from basically the same material as the CA's, but unlike the CA's are not subject to twistage. Their function is in a direct (or nearly direct) back-and-forth motion along their length. Since twisting is the enemy of the CA material and the Watts links are not subject to such forces, I really and truly can't see how the stock construction is any less stiff (in the direction of it's function) than anything else.
Given the slight curve of the links, it's possible there's a tiny bit of bowage in the direction of the curve, but I imagine that would only be under enormous load like say at high speed on a circuit track.
If I was an avid auto-crosser like say Jeremy (jdando), I'd put em on. For my occasional track time and daily driving I can't see an advantage.
To qualify, this is coming from 20 years worth of hydraulics, air suspension, and lowering. I've had to build entire suspensions from scratch and had to rebuild ones that were hacked up by the first guy. I think in terms of strength and safety FIRST. If you get strength and safety, performance is all tweaking. I only say this so you can see my thoughts are not merely speculative.
Best to you on your decision.
