Answer:
You can run full duty cycle digital modes at 100 watts.  We have tested key down for 1 hour and the PA power transistors did not exceed their temperature specifications.

If you are rag chewing on digital modes where the transmissions are long and the breaks are short, then as a margin of safety, 50 watts is a good output power level unless good operating practice dictates to use less wattage, like for PSK31.

I'd monitor the PA temperature by bringing up the Information window using <SHIFT>+<CTRL>+I and not allowing the temperature to get into the red for long periods of time, indicating the PA is above the recommended operating temperature.
