Found out yesterday that 3/8" may be quite overkill. The 8274 comes equipped with 5/16" at 150. Granted, it will be going on a 9500 winch, but I really doubt it'll be any more powerful than the 8274. The other winch is a 8000, so it'll definitely need 5/16".
That being said, I don't winch too terribly often and it's usually pretty messy when I do. So, maybe run 3/8" on the 9500 and keep looking for 5/16 for the smaller.
With all that being said, let me know if you'd like to get rid of it. Thanks!
