PRails-Vintage Hot Stack-'59 Trembucker Wiring Questions

[dubzga]

Hey everybody. Long post but hoping for some advice here on a superstrat type guitar I'm building from a Harley Benton HSH Fusion III. Based on what I'm looking for, I selected P-Rails (no tripleshot) for the neck, the Vintage Hot Stack Plus for the middle and '59 for the bridge. The guitar comes with a standard 5 way switch and one push-pull pot (tone) and volume isn't push-pull. I picked up another push-pull as I'm looking to do series/parallel and selectable coils for the '59 & P-rails as exactly as outlined in the link here. Primarily because I want to be able to select between the P-90 and rail on the neck but since I've got the 4 wire '59 and the add'l push-pull I'm going to do it on the bridge too just for grins.

So where I'm looking for advice - I'm thinking some of this is pointing to a superswitch:

#1: I didn't realize the Strat pickup is also a 4-wire, allowing for the selection of either the noise cancelling both coils or just the top coil for the more traditional strat sound. Like the bridge, I've got the wires so I'd like to wire in the option. I don't mind drilling a hole for a switch or additional tone/push pull..leading to the next question

#2 I'm concerned about matching tone caps with this configuration. If I add the second tone pot, is there a way to isolate the tone caps for when the strat pickup and just when the humbuckers are operating in single coil mode?

#3 The Vintage Hot Stack does not come in a RWRP configuration. Will I need to flip it to keep things in phase with the other pickups?

#4 Last, some people flip the P-Rails so the rail is closer to the neck. On my strats I use a lot of the neck pickup and I'd like to approximate that for the 'rails' setting. If I flip it will I again be running into a polarity issue with the middle pickup.

TL;DR Building HSH super strat, comfortable with wiring but just need a little guidance for a few customizations I'm looking for to provide selectable coils, ensuring polarity is correct and potentially isolating tone caps to just specific modes of operation. Thanks!

bump, I know it's a lot of asks just looking for some pointers

you can split the middle pup to the top coil if you want, it would be useful to do so if you are combining it with the split buckers to get humcancelling

i use the same value tone cap for almost everything, there are no rules. i prefer a .022 most of the time, but sometimes ill go even smaller with a .015. you could wire things up to switch cap values when you split things, but i dont see much benefit

for a duncan single coil, you dont a need rw/rp middle pup when splitting with humbuckers, i kinda assume its the same for a stack?

physically flipping the pup does not change the phase. i ran my prails neck flipped, makes the rail coil slightly bigger sounding but its a pretty subtle change

Very helpful, thank you Jeremy!
