I also have a carbon Elite after having owned a carbon Mako6.
I do find the Elite slightly more twitchy than the Mako6 - especially in very strong head/side-winds. On the other hand, I find the Elite bucket extremely comfortable and that gives some confidence even in rough conditions.
I've also paddled the 14kg V12 as opposed to the 10kg V12 Elite and I thought the heavier boat noticeably more stable.
In my opinion most super-light boats are more twitchy then their heavier counterparts. (I didn't find this with the Mako6 though.)
Going back to your questions:
1. I don't think so.
2. Yes, in my opinion.
3. Yes, in my opinion.
