Tool - It is pretty flat but coarse bitumen, i went for a gander last week, and it appeared to be quite slipery, although it has sat unused for quite a while. Steve has a blower so that should get rid of most the crap, and i believe they sprayed it with sugar water, so going forward grip should be ok,
could be a good place to use up all my old slightly chunked foam tires at clubbies.
Geeza ran foams on both gas and electric but chewed them up quite quickly, but i believe they were eagles and quite soft compounds with traction additive on them.
Drayton ran some orion rubbers, and after 4-5 runs they still looked in pretty good nick but it was pretty skaty for him. So i guess start out with foams and go from there.
