To clear things up....

Schumacher minispikes are a shorter stubby spike, whilst ballistic spikes are longer and more flexible.

Schumacher green compound is a natural rubber compound, whilst yellow and blue compounds are synthetic. Blue is overall hardest, and I would say yellow has similiar characteristics, just softer. Green is totally different, and tends to get used in wet and damp or very slippery worn grass...

Ballistic compounds are all synthetic...
Pink is softest, blue hardest, green medium.

Green ballistic tyres are used the most often in damp or dry conditions on both astro and grass. They tend to wear quite well and seem to last longer on tracks with concrete or tarmac sections. Blue is used very infrequently, only on dense very high grip grass really. Pink is also used very infrequently, only on greasy slippy astro or loamy clay tracks.

What I am saying is tyres and tyre choice comes down to testing/experience, and can be a black art.

To cover you though, I would get a set of the following:
1) schumacher green minispikes
2) schumacher yellow minispikes
3) ballistic green minispikes (with some schum green slim minispikes if your doing 2wd for the front end).

4) a spare set of wheels and foams not glued up, with a set of yellows ready for action
