Of the CF poles in your review, I have only used the MSR Overland Carbon. The field results I had with these were not entirely satisfying, even a little disturbing. At least one of these points may apply to CF poles in general, especially those of smaller diameter.
I experienced separation of the lower shaft portion of one pole in a sudden and unexpected fashion. The break occurred unexpectedly, While the pole was slightly loaded with my weight, the tip was not trapped or bent. My best guess (and I've discussed this with others more knowledgeable about CF) is that the pole section that failed had been pre-stressed at some earlier point, perhaps by the tip catching while I was walking, resulting in a momentary bend. This can cause a loss of integrity to the structure of a pole section, without any visible sign. CF fibres separate at the effected area, creating a potential future cleavage point. When failure ultimately occurs, it does so in catastrophic mode i.e. it is total and immediate, as well as complete. There's no previous evidence of failure, no progressive defect, just a sudden break.
This is a highly undesirable characteristic, clearly, as the result could be a serious fall. For example, if the pole is being used to hop down a small ledge, a sudden pole breakage could easily result in trauma. In this instance, no harm was done, but my confidence in the poles was shaken. MSR were very good about replacing them, but I ultimately decided to sell them.
Lay-up (the way that the layers of CF are embedded in resin) is probably extremely important to overall durability, and poor lay-up may result in compromised strength. This field is really beyond my purview. I will remark that I've used CF kayak paddles for several years with no problems (and they are a delight), but these are, of course, far more massive. In my opinion, the cost/durabilty ratio of CF poles vs. standard aluminum is something to be considered carefully.
A further problem with CF sectional poles is that it is difficult to achieve a truly positive lock with narrow-diameter poles. I experienced a fair amount of annoying slipping with the MSR locks, and also had one lock section separate irretrievable within the pole. Slip is much more than with an aluminum pole. This may be avoided by better engineering (I have a BD CF/Aluminum composite pole that uses the flicklock mechanism, and that works well).
A final point to be considered is the weight of the hiker plus pack. I'm about 215 pounds, and with a pack fully laden with water for a dry camp, I could be as much as 235 to 240 pounds. Since one of the functions of a pole (the main one, in my region, where slick, steep trails are the norm) is to help recover balance after a slip, this load may be suddenly and forcefully transferred to the poles. Will they take it?
