I think The yellows are fine for daily driving street. better than the stock STI pads for cold bite. If you are never going to track than the greens are better. but given that you have Free yellows. ROCK EM
Cold days just drag your brakes very briefly or do one test stop when you get going about 7 and you'll be money. If you park in parking lots and you drive carefully through said parking lot , chances are you will put a lil heat into those pads before getting onto a road and be just fine. (Seems to be my experience with them)
honestly after just 1 second of brake drag when they are completely cold makes their cold bite good. and i don't have to re-drag later on while driving. I commute on these 100 miles round trip when i drive in. with long periods of cruise control (20+ minutes) and don't have any issues.
