I've been using Komperdell and Leki CF 3-piece poles for six and five years, respectively. They've taken all the abuse I can throw at them, have doubled as shelter supports (including siamesed as a pyramid pole). They're scraped, scratched and nicked up, as one might expect, and are still fine.
My conclusion is it's not the material, it's how the material is spec'd and the overall pole design. A properly designed and made CF pole should not fail.
(FWIW I've used aluminum and yes, bamboo poles too. CF for me, thanks.)
