"Hot" pickups tend to sound muddy with a bass IME, so I would avoid them, and also avoid Strat pickups with ceramic bar magnets.
I tried and took notes on alnico rod Strat pickups with the following specs in a short scale solid body bass :
A) 4.80K (wire unknown, probably 42)
B) 6.38K, 43 awg
C) 7.70K, (about 5+K of 42 with about 2.5K of 43 added)
D) 10.79K, 43 awg
Short reviews:
Switching pickups A and B, I prefered A at the bridge and B at the neck to A at the neck and B at the bridge
B at the neck and C at the bridge was my favorite, it sounded real good
D sounded muddy, less defined
It would also be worth your trouble to try different caps with and without pots.
You should also consider the rw/rp deal, for example, with the Texas Special set you'd need to use the middle pickup with either one of the others so it won't sound bad when both are on. I think I've read they're wound with 43, but can't say for sure.
You could also try various cheap Strat pickups from ebay.
What's the deal with 43? I don't know, but the Fender SCPB pickups are wound with 42 and very similar to Strat pickups and people are changing those left and right...and some still aren't happy.
Edit: I've never used Texas Specials in anything, so that's just a guess on my part.
