Yeah, BKP don't make any Strat or Tele sized humbuckers - neither the stacked type nor the side-by-side type like the Hot Rails. So if you really want humbucking pickups for your Jackson, BKP don't cover that area.
If you don't actually mind single-coils then there's plenty to consider. I've always been fussy about single-coil hum so I've tried lots of things like Duncan stacks, Lace Sensors, Joe Bardens, Kinmans and DiMarzio HS and Virtual Vintages. But I have to admit true single-coils sound better (although the Kinmans and VVs are very good!). I've just caved in and bought a set of Irish Tours (but not wired them up yet).
If you're after something powerful and more capable of competing with humbuckers, Trilogies might be worth a look - I've never tried them but you'll find lots of info on the forum.
