Danworth Ground Anchor. What Size / Weight?

[Swaney]

Just picked up a cheap winch 7200lb (3,200kg approx) pull for $395 from TM. My truck is around 1750kg so I figured that the winch should be good enough for my setup.

Now thinking about anchors. After some googling and some quick reading it would seem the 18lb (8kg) Danworths are decent enough to pull LWB Landrovers out of holes.

Looking on TM there are a few Danworth's which weigh about 4kg - i am thinking that they are probably not big / heavy enough for pulling a SWB Pajero outta a mud bog. But really I have no idea.

What anchor do other people use? I have found some plans on making a pretty heavy duty sucker but looking at it it is going to be cheaper and quicker to buy a pre-made danworth anchor which apparently does the job nicely.

Thanks for the help!
