Greenstuff are great for fast road use, but they're quite soft.
If you do the odd trackday/drive like a loon, then go for Redstuffs. They're a bit harder, so will last longer, although they're not so great from cold as the Greenstuffs.
IIRC, Yellowstuffs are like full race pads, so probably not that suitable for you matey.
A good alternative to Redstuff is of course Ferodo DS2500, which are outstanding.
