I'm delighted to hear you like the Porterfields.
I would imagine they were the R-4S, with S standing for street, I'm pretty sure they're the ones I use (will check the boxes tonight). The R-4 is more for race applications and requires a bit more heat into them to get them working well. If you get addicted to them it's well worth buying a small quantity from the States, they're approximately $99 over there, although saying that £120 was very reasonable, I've been quoted a lot more than that in the UK before (circa £170).
