I run a tigershark on my disco, why are you thinking of the 11500? i run the 9500 and its never let me down, i also carry a pulley block for when im pulling other folk out of the really sticky stuff. It has always been strong enough on single line to get me out of anything, and i mean anything, like mud upto the bonnet edge, really sticky stuff.
I chose the 9500 over the bigger one because of the line weights and the overall weight of the kit and as i said its always been man enough, not the quickest winch in the world but strong and good construction for the price and its been very waterproof so far.
