I've got some on the way to replace the 15 year old cable on my milemarker. Should I be worried about drum heat on this older winch? I know that they will generate the most heat while powering out, so I will have to avoid that; but should I be concerned with regular use? Does anyone make a heat shield I could put either on the first 15-20 feet of rope, or something to wrap around the drum under the rope?
