You are probably right, makes sense, the cams support the built in shape better than a no cam sail when the mast is not optimal.
Here I think people can get a good idea of the different characteristics of Element/NCX/Gator
and then click the Compare button, and then click on Element and Gator model
There are pretty new test results of these sails online too (NCX test winner)
Regarding the Element I think there is a big difference between the 09 model and the first versions of the Sail .
