pins are awesome round there and will be ok at the astro masters i think (i don't think they go by the brca tyre limits), but Chris will be talking about spikes cos that's what we run at the nationals.
i think most of the top boys will still be running spikes during the winter, as it's good practice for the national to get the right setup with the tyres allowed in the nationals (and regionals for that matter).
...although we don't know what tyres will be the allowed ones at the nationals next year
