LOL.
The Himount is an Awesome Winch that works great. As you have explained though they really are at their limit or beyond their limit is standard trim. Going straight to a Double Line pull is not unreasonable if the winch out is not a simple one. That would be my goto.
The Comp guys have spent Bulk Coin building a Himount to be way more than what you see in those pics. Ratio Changes, Hellfire gear sets, double motors and 24v. Gigglepin Brake shafts and GP Brake shoes. GP Solenoids and GP Free spools. $$$$$
Be happy to own a HiMount. Use it, double line pull it.
