Ok- I am puzzled- if one uses a single pulley to, say lift a 100lb load, it still takes 100 lbs of force to do it. IOW if 2ft of line is pulled in the load still moves 2ft.
It does seem places like Warn's site says it double pulling power so I'll have to agree I was wrong. I still don't get it though!
Off to study.....
