.....But... Any winch is going to add weight and that is going against the trend of keeping light for better handling and performance. Some of the fellows I've asked locally claim they have never use their winch after many years. Just got back from a 10 day Jeep back country trip with 14 other Jeepers and never needed a winch, although one guy readied one once but we got the stuck guy out with a few placed rocks....
Weight on the very front (within reason) isn't a bad thing - it can keep the front from unloading on a steep climb. That 75 pounds of a winch can help neutralize the spare tire weight hanging on the rear.
The very last choice for me in a recovery is a winch due to the time involved. First choice is to stack rocks (like your situation), second choice is a strap but sometimes those two options aren't possible once you start doing the harder trails. In those situations only a winch (or two) is the only way to get somebody out of trouble.
But for those winching situations, you really need a 100% dependable product. One time in St. George two of us were pre-running a hard trail and my friend took an optional route and got in a very precarious situation, he was rocking back and forth on two opposite tires at the edge of a small canyon.
We were afraid he was going to roll two or three times down the canyon. I got a winch line on his corner and pulled him back and then kept tension on him as he made his way off the edge and down the trail. A short diversion off the main trail for him almost turned into a very ugly situation.
So the moral of the story is, for some situations you really
need a winch, and it needs to be 100%
reliable. Even on a Forest Service road you might need to pull a blowdown off the trail, pull somebody out of a mud hole (too far away for a strap), etc. Some recoveries will need two winch equipped vehicles.
