So....instead of offering your help to the OP, there's going to be another war about this issue? You're obviously both educated on the use of synthetic lines, and both have some very valid points on the use of synthetic line. The research that you have both done on this subject is obviously immense, and I find it great that you're willing to share it. It's amazing at the expertise on this site (and many others) and the wars that can start from it all. I've been caught up in it in the past, so I'm no angel but it's disheartening to see it happening more and more on various boards.
I agree with you both, I'll use the heat guard when I spool my amsteel blue line onto my 9.5XP (thanks again Martin!), but I also know how I use my winch and don't power out save for taking the tension out of a line so I should never actually need it. However, it's there in case I might. So with that said, how about that for advice for the OP. Install it just in case, and hopefully never need it.
When installing the synthetic line on a winch, you'll most likely need more that 4-5 wraps on the drum...I'll personally be sticking with about 6-7 unless I really need the extra foot or two of lenght and then it will be situation dependant. This is because the synthetic line doesn't bite the drum as well as wire rope, and the extra couple wraps should give it the friction needed to stop it from pulling on the little set screw that holds the end of the line on the drum. There is a cool (and really simple) device out on the net that physically stops you from being able to spool off more than you should, but it takes a little bit of finger work to install it. Here's the link for the install instructions: http://www.muddyoval.com/articles/ge...peretainer.htm. I've made this with nothing more that a scrap piece of 1" tubular webbing sewn together in the middle. It works well, but I have not had a chance to use it on the truck as it is currently sitting in the garage getting a SAS and new suspension.
What ever you do...think it through from start to finish, and even to the point of clean-up. If something doesn't seem right, then it most likely isn't. If it doesn't feel safe, then don't do it. Any second guesses....get a second opinion.
