What compound full spikes from the old days

[samd]

Now im going back a bit now to racing at haltemprice sports centre in hull about 13/14 years ago. I remember the tyres to use were schumacher full spikes, cut down then ragged around the car park for a bit first but i seem to remember they were some sort of special compound, not the usual blue/green/yellow - anyone know what im talking about or is my memory mush?

They weren't at all like yellows. For a start they had way less grip than yellows!

CAT tyres used to come in Soft or Hard. Hard could be used for a nuclear blast shelter, but had no grip, Soft had more grip but died in a meeting or two on tarmac.
When Blues came out, they offered Hard durability but Soft performance, and sales of softs dried up. Pretty soon you could have any compound as long as it was Blue. A few die-hards still used Softs as they said they had a little more grip, but the appearance of Green killed that. Greens were grippier than Softs but lasted longer.
