Too many to choose from

Ok I only use my RY bridge splits combined with an IT middle as I have it wired autosplit on a 5 way with HSH PU combination. I like what I get and I think it works. Still, there is one thing I recommend cause half a HB is still no SC (the more powerful and dark the PU gets the less of an issue this is, which is why the crawler rules for splits). Just in terms of winds and such it does not add up. Yet there is one thing that can lessen the difference.
Do a PRS style split and put a resistor in series with the wire coil that you send to ground (turn off). That should be the green and white wire if I recall. That way when you split the coil does not completly shut off, just turned down a lot. Like using a volume knob in switch form for only one of the two coils. This results in getting the SC character from the main coil with the other, turned down one, contributing in adding back some output, lows and taking out a tad of hum. That makes for a sound which is much closer to a real SC I find and makes the jump not as extreme.

Super easy to do as you really just need to put a resistor between the end of the green and white wire and the point where they are supposed to go in the split wiring you are going to do. PRS recommends 1k Ohm for the neck and 2k for the bridge. Works, but I am gonna next try 2 and 3 as I have my PUs also turned around so the split coils are the outer ones making stuff even brighter. Anyhow, try 1 and 2.

I hear there also is a variation using a capacitor where you donīt turn down the volume but lower the resonance peak which I will also try (hopefully) soon. Might be even better for what I want.

If you think the Floyd bridge is really affecting your tone, you might want to consider one of those Sustain Blocks from Floyd Upgrades.  Might give you more options in terms of pickups.

Thanks agent orange that sounds good,  cheers.

Kiichi thats some pretty cool stuff you've suggested there,
Definitely going to try that.
Have you tried wiring the humbucker in parallel before?  It's something I been looking at also,  but as I say will definitely try out your suggestion above.

P4vl I do think the Floyd is affecting my tone somewhat. There's not enough stability when playing the low strings moderate to hard, low notes mushing together and the attack of the string/note is being lessened I think. Do you think the brass blocks will help with that?
Just been looking at their site and it does look promising, one of those big brass blocks may also fatten the sound of the guitar up complementing the rebel yells tone. Mmm

I tried parallel wiring on my Mule neck PU, as that lends itself a little less to splitting as it is low output. I kinda like it, works well, but I still prefer splits personally. Worth trying both though as both make for good SC like sounds.
Donīt expect a night and day difference from the resistor thing though. It is more among the lines of 2-3 turns of the height screw I feel.
