Handle -- Carbon or No?; Nevin or Accurate

I'm pretty set on getting the Accurate Catalyst rope (A-line w/ 5 3' takeoffs), but not sure on handles. I've done lots of searching on this site, but haven't found the answer I'm looking for.

1) Will the Carbon handles break?
2) Which of the Carbon handles is the most durable, most comfortable? What would you recommend? I know its personal preference, but input helps. I liked the Catalyst carbon handle (smooth feeling), but have heard good things about the Nevin. If not for the carbon, I think I like the Premier handle the best.

Thanks.
