OK, so I e-mailed Tim and he recommended a nailbomb which took me back a bit.
However I have a great deal of respect for his opinion, and am now in a quandry.
I'm gonna order on monday, so if anyone wants to weigh in on the tonal differences regarding the sound and versatility if these two pickups, holydiver and nailbomb, i'll post pics and clips when they're fitted.
