ive been tuning my c line relentlessly and its still very stiff but not so slick. in my experience the easiest thing to do is get a S 4/5 grams less or more than your current S for turnover or fade. i think even light c line will be more stable than almost any S line. at some point ill pick up a 165 c and check just how different they seem to be.
