I've had a set of irish tours in my alder bodied Jap strat for 2 years now and they're great.
Admittedly I've never tried any other BK pickups apart from checking out the sound clips on the forum, I went for the Irish tours as I love Rory gallagher, jimi hendrix, srv etc. I was slightly worried that they would be too much overkill for more sensetive playing such as Dave Gilmour type tones but they can do everything - hot texas blues, mega heavy metal, subtle twangy blues, chilli peppers, buddy holly, comfortably numb solos - 1 and 2 !!
Although they're aimed at getting you in the same ball park tone wise as Rory Gallagher they really are very flexible tone wise - classic strat distortion, grinding neck pickup, sparkling chimy cleans etc. all you have to do is just back off the vol. control and they clean up great.
