In the BKP range the neck and bridge pickups are generally completely different.
When there is an option for an Alnico V magnet or a ceramic magnet in the bridge position only the magnet changes, not the winding.
The only neck pickup with a ceramic magnet in the range is the Painkiller neck.
The only bridge pickup with alnico and ceramic magnets in the same pickup is the Juggernaut bridge. All of the EQ charts on the site are bridge only. The neck is often very different. The videos usually have some neck pickup in them but it's mostly bridge
The youtube video I posted shows the Nailbomb set in bridge, middle, and neck positions
So, the ceramic and alnico versions of the bridge Nailbomb are the same except for the magnet. The neck Nailbomb is alnico but it is a completely different pickup.
Personally I think the Juggernaut bridge is very high output for the neck position and you might have problems balancing it with whatever you put in the bridge position.
