Have you got the 500T and it's friend in there at the moment? If you like the general vibe it has already, but want "better", I think I was recommended Cold Sweat as well a couple of years ago.
Instead I went a different route, using pickups I already had in other guitars.
Riff Raffs - these worked very well. In fact, I think I posted a "they're never moving again..." at the time.
Mississippi Queens. The guitar the Riff Raffs came out of received these initially. Then one day I swapped the MQs into the Explorer to see what would happen... and they haven't moved since.
I find the MQs do a good enough "humbucker" job for what I want, and they just fit me and this guitar so well. However, I'm a blues and 70s-rock sort of guy. They might not be enough for 80s rock, you'd probably want to rule out MQs.
I'd happily try to to use Riff Raffs for it, but I suspect that Cold Sweats will get you closer (I've no experience of them though)
