Schumacher yellow minispikes for normal worn and dry grass.
Ballistic buggies minispike in green are the one most choose now in wet grass.
at Batley (part grass/part worn old astro) we use those.

Schumacher full spikes in "soft" for retro grass/mud racing with an old school feel. http://www.rccarshop.co.uk/index.php...pike-rear.html

there is also a newer full spike in Yellow compound: http://www.rccarshop.co.uk/index.php...-2-yellow.html

Yokomo TR32's in the wet (if you can find them now).

Some run schumacher minispikes in silver, but not used them myself.
