In the next couple of days I stopped by the local Fire Brigade and asked them what they use..... The long and short of it lead me to a place called "Quality Chain", out in Surrey. After putting it off for a few months I went to Quality Chain, got their opinion and they made me some chains. They set me up with what they make for logging trucks, modified to fit my wagon. The zig-zag pattern is to make the ride more comfortable, as well as providing better traction.
Oh, and they like their dogs, whom are very happy members of the crew.
They are really good guys, who are into what they do.
