Tires help and advice appreciated

[ASKay]

Hiya all, now I have the car SX3, built, radio, batteries, speedo etc... I was wondering what advice people would suggest for tires... Note... I have never raced on Astroturf before...

I have some mini spikes yellows....
I also have some mini pins yellows....

So what should I have in my box for wet astro turf...
What about silvers (I believe these are softer than yellows, am i correct)...

what do inserts offer... it is not something I used to use, all those years ago????

Any help would be good... do not want to turn up without some gear to get me out of trouble for lack of balance of grip on the car....

help and advice would be much appreciated...
