Look, instead of asking about bunch of pickups how about giving us a little information about what TONE you want? All BKPs are good and many are very versatile and sound good in les pauls, so it's really not about "which one is better for hard rock/metal". I've got Mules and Crawlers in my guitars and though the two sets are vastly different they are both great for all the styles I play, but in different ways.
What direction do you want to go over the stock pickups? Brighter, warmer, fatter, more/less grind more/less mids? Give as much info as you can. (and keep it in one thread, please)
