Please help me sort this out

OK, I have a HSH guitar (Ibanez RG1570). I want to outfit it with a full set of Duncans and have the humbuckers split with the SC in positions 2 and 4.

The Stew-Mac site gives the following info about Duncan humbuckers:

Adjustable coil magnetic polarity = South
Slug coil magnetic polarity = North
Coil windings = clockwise

And for standard Duncan single coils:

Magnetic polarity = South
Coil winding = clockwise

So, we would want the slug coil to stay on when splitting the bridge humbucker so that it would have a magnetic polarity that is opposite that of the middle position single coil. However, this would still not be hum-cancelling since both the humbucker's slug coil and the middle position single coil are wound clockwise. In fact, wouldn't this produce an out of phase situation that would sound really weak?

Am I missing something here? Is some of my data wrong? Is the solution to use a RW/RP single coil in the middle position (north polarity + CCW wind) and use the adjustable coil from the humbucker (south polarity + CW wind) when splitting?

Thanks in advance for any help you can provide.

Re: Please help me sort this out

The StewMac info referrences the bobbin rotation, not the direction of the wire of the coil around the bobbin.
Phase is electrical, the wind direction of the coil (and the magnetic polarity) does have a bearing on the phase of the signal produced, but the end result of the phase is determined by the wiring of the coils, not their wind direction.
The std. SD HB's (slug) inner coil will be in phase with the std.
Spend some time reading about how humbuckers work in the FAQ section of the main site, as all that's covered.

Total & complete nonsense...

First-off he didn't specifically answer the question, just an condescending bureaucratic response.

Secondly, there is no specific info on humbucker bobbin wind direction "in the FAQ section of the main site".

There's actually info on the "The Stew-Mac site", even if it's incomplete...
