No, not really. The most recent PIREP closest to us said no ice. After launch I knew we were within five minutes of the first approach where we could immediately exit the conditions if needed. I knew we had VMC 400' below us so had the accretion rate been any worse I would have immediately descended out of the muck. So, no....faced with the same data, I'd likely make the same flight. That said, if someone was launching in a FIKI machine ahead f me I would have asked and waited for their report before launching.
