YMMV, of course.

And cost-wise, remember that just because it's expensive doesn't make it better. Most $30-40 alloy bars will be less likely to ever fail than a cheap $80 CF bar. You can get them for cheap, but if you want them built out of the nice stuff by a company that might actually cover some failures under warranty, the price tag goes up quite a bit.

It's probably the more paranoid view, but I like my collarbones a lot.
