Thing with that is that symmetrical humbuckers do not change much if at all noticably. When the coils are offset however (asymmetrical), there is a change, which IIRC should usually mean a tad rounder on the neck if the slug coil is the stronger one.
The Jugg neck is based on the VHII neck, which IIRC is offset. So if I am not mistaken turning it around should make it rounder and fuller as the more powerful coil is closer to the neck. It is hard to guess how big the difference is, but I recon it is noticable. Could be great, could not be your kind of thing.
To be save though IŽd ask BKP themselfs too.
