It would be good to see how strong it actually is, in theory it would be stronger than the 550lb to allow the safety margin on the manufacturing etc.
Toddy also raises a good point on how much it catches, generally (except for when you want it to) the cord that slides through the leaf litter and around the trunk of a tree smoothly is much easier and nicer to use.
Womble_Lancs managed to tow Spikes 650cc Honda to the moot with some 550 a couple of years back.... I was impressed enough at that !!
