V8 I'll have to do some more sleuthing on the filtertrons. The internet seems to think that while the DCR is low (4-5k), the magnets are much more powerful which produces an electrical signal of similar magnitude to that of a humbucker.
I don't really have much experience with fancy switching, but my LP has push pulls for coil taps and that has been handy (see recently completed Gil-MORE challenge). Also, even if you do have fancy switching you always have the option to not use the fancy bits and to just stick to using the volume/tone knob.
The "pure" P-90s like the P94s will obviously simplify the wiring a lot, but the Bluesbuckers and P-Rails seem to be made with splitting as an expected configuration.
