My current choice is (if you want standard strat sounds) Injector Bridge, '58 or '61 middle, '67 neck. That can vary some by guitar if the guitar is very bright or very dark naturally. I also generally use a .0015uf cap on the bridge tone, second tone controls all other positions and is .0022uf. In bridge position I use a switching system that can put the bridge in series with either middle, neck, or middle/neck in parallel, while also disabling the bridge tone control and rolling off what would normally be overwhelming low end when doing that; and it doesn't affect the other 4 positions. 4th position has a 3 way switch that does middle plus bridge, middle plus neck, or all 3 on.
I also really like that combo subbing a Fast Track 1 in the bridge for a P90 (albeit much improved P90) sounding bridge, or Chopper in the bridge if I want a PAF type bridge tone. If I'm doing either of those, I don't install the series switching part, not really necessary.
