Synthethic winch cable...fitment question.

I have a Warn 8000xi winch and my steel 5/16" cable is about shot. I am going to go with a 3/8" synthetic line to replace it.

Does anyone know if 100 ft of 3/8'' synthetic line will spool up completely on the drum? If it was 100 ft of 5/16" then I wouldn't be concerned...but with the thicker diameter line, I am wondering (?).

Also, I am considering the Viking combo fire line, but can't decide if that's overkill. The first wrap of this line is heat resistant to 450 degrees (I think). Has anyone experienced a synthetic winch line "melting" onto the drum? I never realized that heat may be an issue with synthetic line, however...if anyone has seen this happen ...please advise. Thanks for help on this.
