FWIW, I play an all mahogany 7-string in a rock/pop covers band and I have a Holy Diver set in it. I think you'll be really happy with a Crawler set too (I've had a Crawler bridge before but not tried a neck crawler), but I do love the HD set. The bridge is hot when you want it to be, but has plenty of dynamics and warmth, and the neck is actually quite vintage sounding (to me, anyway), but the two pickups together is a beautiful mix - ballsy and fat but not bloated, almost a combination of a humbucker/single coil sound. That's with a fairly low gain sound that I use for stuff like Sheryl Crow, etc, and for cleans. It really is extremely versatile. I found the Crawler to be a good sound too, but to my ears it lacked a bit of character somehow. I think the HD is probably fairly similar in terms of frequencies and output, but I find it has a more unique character to the sound, which I prefer. Having said that, the crawler might be nicer when split - I don't tend to use the split sound on this guitar much, because the full humbucker sound is so good and the split sound is quite a bit quieter.
Just my thoughts....... 
Thank you so much for your input, it means a lot. My initial idea for this guitar was definitely also the holy diver, but for what I remember, it's a little more suited for heavy metal and rock purposes, lead playing, which for sure it does well for what all the reviews are saying. What you must not forget, is that my guitar is a maple neckthrough with alder wings, and ebony neck, a fairly bright superstrat, compared to an all-mahogany, that carries a much warmer and meater tone. Thus will the meaty crawly in already meaty guitar like mahogany, might come off as a little dull in your case, whereas the Holy Diver will be a much better match for that kinda guitar.
Of course I have not owned any of the two, and only retelling the same stories of what I hear on the internet, so don't take my word for it completely.
I still think, that for my guitar, the Crawler is a really good bet, for making a good all-around guitar.
