Dave I think you missed the point on winch speed. Although relatively fast, a 9.5K HS would not be anywhere quick enough for a winch challenge. They're often running 8K high mounts at 24 volt with with upgraded motors, plasma rope, custom gearing & even water cooling.
Speed is important as I mentioned to avoid over run & to recover a vehicle out of muddy water. (I for one would prefer to get out quickly to avoid filling the car with mud)
After looking at Warns specs the 9.5HS outpulls the 12k right accross the full load range & even when its double blocked it's still quicker at 12.000lb load. Where the big winch wins is it uses around 15% less power but because it's so slow its running for longer so the end power usage is pretty much the same.
& it's not just 30 seconds you save. It takes almost 5 minutes just to wind in all the cable with no load on a 12k & less than half that on a 9.5.
The 12k is 26 kg heavier, slower, more expensive & I question that many bull bars for an 80 series would be rated to take 10 tonne. (full load double blocked)
Agree totally that the high lift is a great unbogging tool only surpased by the mighty shovell;-)
To further answer your question Howard as to which motor size is best in the 9.5K range for example the XP with the big 6hp motor is around 5 to 10% faster under load than the 4.6 hp HS although surprisingly is 60% slower unloaded. This extra speed under load comes at a big cost to power consumption varing between 10 & 60% more.
I suppose what you have to concider is do you need that extra line speed & if so will your battery system supply the extra power?
