Brake and Fuel Lines - 69 'Cuda 340 FB

Looking for some advice. I'm thinking about buying complete brake and fuel lines from Classic Industries (CI). Anyone have experience with those products? I heard SS is a pain to work with and the original material is better....Anyone agree of disagree? Any pointers or advice for all new brake and fuel lines? I'm working with a blank canvas...I don't even have the old ones on the car, so flying totally blind. Any other options (sellers) to consider other than CI? Any and all advice is welcome.
Thanks,
Rod
