You only have 60% the pulling power on the outer most wrap. It's got the same motor as the 12K, the 12K has lower gears. I wouldn't get anything less than 12K. Many winch failures are due to overload or exceeding duty cycle. Only my 12K Warn platinum tells me I've exceeded the duty cycle (which I've never come close) It also tells me when the voltage is too low. My other two Rubicons sport 12K SuperWinches, I didn't want to shell out the coin for 12K platinums.
Even with my 12K winches, I almost always use a snatch ring to almost double the pulling power and get an extra anchor for free.
