Well, ask 10 experts for an answer and you'll get 12 replies.
I bought my new winch yesterday from Goodwinch, well I was sort of passing their place in Devon. And they gave me a kill switch wired with 35mm cable. I asked them why you'd do this as this would then be a restriction (for want of a better word) in the wiring. No, apparently not as the factory winch wires are 35mm too. I did not know this. Now we can do all the calc over and over again and I do understand the maths, but I also have to take account of a group of very experienced winch people. They workshops there are a thing to behold. Talk about experimental. They have even made a three motor winch.
They have tested winches to destruction there and their view is that I will fry the motor completely before I ever melt the cables. So I asked about power getting to the motor and wouldn't 40 or 50 mm cable be better. Their view on this particular product is that you will actually create problems with the motor doing that. 35mm IS the right cable for that winch under the sorts of winching that I said that I would be doing. I had LB very stuck on occasions and never had the cables getting hot, nor did I ever stall the motor. They also put me off buying the 12 000lb version and urged me to go for the faster 9500. They showed me the tests that they had done with the 9500 and the evidence spoke for itself. They have an 80 there which belongs to David and that has a 9500 on it. So, I went with that and a prebuilt winch tray. They even chucked in a remote! Whoo hoo. I did go with the thicker rope, not really because I was worried about the tensile strength of the 9mm but the thicker rope also contributes to free running spool in speeds which is handy at times. So we should have a winch on for next weekend but I will only have time for a temporary girder style bumper. I know we aren't winching, but hell I have it now so it's going on and that's that.
This is not really intended to start a debate or worse still, an argument, but there are times when calculations look right and make sense and there are times where I would lean toward experience and advice from someone I trust. Still going with thicker cable for the charging system for the reasons that we have discussed in another thread.
