I've stumbled upon the Spider Chassis by Pro Track. I have never heard anyone mention this chassis in the past and since I usually go straight to the chassis I am looking for, I haven't run across it while browsing the shelves of our distributors....till this morning. It's a strangely attractive chassis but seems it would be heavy. Stout but heavy. It's for 1/32 scale. Is anyone using this or has anyone even heard that it is being used?

There is one called a Spider Roller they have that is also 1/32 and a little different.

So what the heck are these things and who would use them for what?
