No, the Holy Diver was so perfect for my RR1T (see
here for my original post) that I've not even considered anything else. FWIW, I didn't have the Savage when I first got heavily into the Holy Diver, I had a Mesa Rect-o-verb - much darker, looser, sludgier high gain sound.
In fact, now you come to mention it, the only other pickup I put in any of my other alder/maple neck-thru guitars was a Painkiller in my KV2. I went straight to Holy Diver in my Charvel 550XL & Jackson SL3 (& love it in those too :)). I'd actually quite like to get another KV2 or an RR1 to put a Holy Diver in.
A Nailbomb would work. I found Feline's advice that it sounds best in bright guitars to be very true - it sounds far better in my bolt-on DK2M & Warmoth alder strat than it did in my Les Paul or PRS. However, I just don't
like it as much as the Holy Diver, not that I
dislike it, but I find the Holy Diver better in almost every way. Personal preference I guess, YMMV...
