95+% of the time when I'm harvesting sawlogs or firewood, I probably use less than 150'. When clearing for a new trail, I'll use everything I have, and occasionally ad a length of chain to that. Often the trail is too rough or has too much side slope to take my tractor on until we get a dozer or excavator in to pull the stumps and put the final grade on the trail.
Unless I have a nice straight pull with good visibility (a rarity in the woods around here), it's very tough to use the full length without an extra person to act as a spotter. Maybe if I had a remote control winch, I could do it alone, but I prefer to have someone within sight of the tractor as well.
"95+% of the time when I'm harvesting sawlogs or firewood,"<< I probably use less than 75', I always try to back up as close I can especially to saw logs. Only place I'd need 200'+ of cable is if was doing mountain logging and yes with that much cable out an extra person for a spotter would be a must for me, other wise my 200' cable would end up in half in no time.
