Splitting "Buckers w/JM tone/vol pots

[Strat62]

I've built a couple of Jazzmaster clones with humbuckers and used the "classic player" wiring circuits that use the roller tone/vol pots to split the humbuckers. This works pretty nicely, but I'm wondering if I'm screwing up using the 1 meg vol and 50k tone pots that come with the Warmoth hardware kit-the only place I know of that actually sells this hardware? Would I be better off with dime-sized 250 or 500k pots?

Maybe I'm not understanding this right but it seems to me it wouldn't matter what you use to split the humbuckers. All that matters is that one coil gets shorted to ground so that only one coil is active. The value of the pot shouldn't matter for that aspect of the wiring setup you have.

Well, how this works is that rather than an on/off situation for coil split, you have a controllable blend from full humbucker to single coil. My question is whether or not I could gain even more control using conventional dime-size pots rather than the 1meg/50k pieces I'm using now. Here's a shot of Fender's diagram that will explain it better than I can.

If it's a blend then I guess the value and taper of the pot would be a major factor. I don't have much information on that subject but I've seen lots of threads discussing that in regards to tone and volume pots and I think that would apply to what you're doing too.

I thought you were doing a "spin-a-split" like I did.

My tone pot is 500K linear. With the pot at maximum the south coil on my neck mini HB is not active (shorted to ground). Rolling back slightly (to about 8 or 9, let's say) gives me both coils, full HB. Below that point it is a normal master tone control. That pot is also a push-pull and the switch gives me series wiring options but that is not relevant to this discussion.
