Which synthetic winch line?

[Alan06SUT]

Ok, my steel line is all frayed and smashed etc. It is starting to get scary when using it! I am going to switch over to a synthetic cable. My winch is the H2 Multi-mount 9.5ti. What size 3/8" right? And what brand? Are any colors better or worse due to UV rays? It will sit outside much of the time. I heard you should switch to an aluminium fairlead as well. Is this true?

Thanks.
