Some people just don't like the Nailbomb neck.
To my mind it is more suited to the thrash metal or hardcore punk player. It's not round or smooth like some of the other choices, and its not quite as dark as most of the smoother sounding ones.
I have the Cold Sweat set as well. I tend to think the CS neck would match better with the C-Bomb than with the A-Bomb. Originally I had the A-Bomb/CS combo in my SG and always found the smooth/rough combination to not work well, but the hairiness of the A-Bomb is accentuated in an SG. When I got a CS bridge for my SG I moved the A-Bomb into my Explorer and bought a Nailbomb neck for it. So after starting out with the mixed set I bought the other pickups to make two calibrated sets.
Other choices I considered for the Explorer to go with the A-Bomb were the Rebel Yell, VHII, Supermassive, and Stockholm. IN the end I went for the matched set, but the Rebel Yell was the strongest contender. Personally I would recommend the RY over the CS for you, as it is like the CS only a little brighter. I think your choice is probably between the CS and the RY
