York Indoor finals .. tyre choice for 4wd and diff options ??

[Colinevan]

Have never raced before at york, so would like to know what tyre choice i should go for the finals this sunday.

I attended the Batley supercup and majorly sufferred from no rear end grip at all in my final so is it a similar scenario here?

Iv got yellow mini pins - although theyve practically worn out and new yellow mini spikes that i would revert to back for the outdoor season @ southport.

What tyre combo will most people be using for 4wd? and lastly do any of you run zx-5's, if so what diff option are you guys running with.

Thanks for your time.
