The problem I have experienced is the VHII and HD pickups sound single coil like no meat
I don't know you guitar nor what pups and electronic it comes with, but what you describe is nowhere close to what I know of BKP humbuckers. I really suspect a problem in your wiring. I swapped my Vox Custom 24's stock X2Ns (possibly the heaviest passive 'buckers you can get) for Crawlers, and I can tell you they don't sound anything like "single coils" or "no meat".
, I believe the volume is 500K, I have a new one I will install just to be sure, Anderson adds resistors and a cap really unnecessary probably.
This is called a "treble bleed", and is supposed to cure the loss of high ends you get when rolling down the volume. Looks like they at least git it right if there's a resistor involved (most constructors just add the cap, and it really don't work), but that's really something I'd get rid of - but YMMV.
But anyway - I don't think this can explain why you'd find RY weak (and let's not talk about HD).
I am going to wire it for just volume and 5way as I don't use the other tone and pull pot features.
Mmm... Pull pots with four-braids pups ? Look no further, you probably got the wiring wrong and have your buckers wired parallel or split. Remember that each brand has it's own wiring color code.
