Two reasons you shouldn't do it on a C1: The radius of the bowden doesn't allow for it and the temp the C1 without the ridicoulos hotend upgrade won't cut the cake. On a B..... it works flawlessly and yes, the results are promising. The optics aren't comparable to Prusament PCCF, but the material is...well.. see the technical data sheet. 

Unfortunately, I haven't printed with PET myself, but I have printed with PPA-CF.I can say with certainty that the bending diameter of PPA-CF is 80 mm. I installed it in my horizontal drag chain from the Prusa XL and it works.Yes, it's true, the tighter the radius, the more resistance there is when pulling the filament through the PTFE tube. The latter is also subjected to more stress.

Needing to print some parts that are specified for PC-CF. Im reading that PET-CF is easier to print at the expense of some impact strength. 

Does anyone have any experience with PET-CF?

Printing on a CORE One. 

Thanks!

What I wanted to add to be careful here. PETG and PET are not that similar. They are both polyester derived but they do not have the same material properties. PETG is softer and more impact resistant. PET is stiffer and more brittle but has a much higher heat deflection. 

Good catch, I was reading a bit too fast there.

The bigger difference would be how the two handles temperature, pc handles higher temp than pet and the more likely reason to specify PC-CF is likely heat exposure, if that is the case pet can’t really replace pc. The next reason to specify PC-CF could be stiffness, here PETG-CF is still softer which can be good or bad depending on the application. Both PC-CF and PETG-CF print well on my core one, I would not pick PETG-CF if PC-CF was recommended due to PETG-CF being easier to print, the difference is not that big on a core one.
