I stayed at 240 because less than that and I can pull the layers apart on a FFCP, but doing the bridges *really* slowly (20mm/s at 0.2 mm layer height) and with a print cooling fan going. I've heard 240 and above is bad for the interior Teflon so I have the Micro-Swiss all metal hot end upgrade, but haven't installed it yet. Waiting for a free moment to take the hot end apart.
