For me, I prefer a smooth sole simply because it is easier for me to sight the iron alighnment. I do have a few C s however but that is not by desighn. A C sole will function with a bit less resistance but not enough to loose any sleep over. Jacob, your observation is accurate, there are many, many videos on the subject and some are conflicting. Best to talk to someone that have used the things professionally.
