Carbon Fiber Nylon

I’m looking into printing with CF Nylon. To get to the required nozzle temp, I read that I’ll need an all metal hot end. I have a Dual Extruder but have not use it yet due to all the problems I read folks are having. However, I also read the Dual Extruder has all metal hot ends? If so, and I swap to a hardened nozzle, is the Dual Extruder the best option to explore CF Nylon or should I look at making up my own all metal hot end for my single extruder?

Thanks!
