I voted for the Duncan JB, SH-4 on your list, but its correctly spaced model for a Strat is actually the TB-4 Trembucker. It uses Alnico V bar mags like your Tex Spec single coils, so you'll have even magnetic field strength, too. The TB-4 is the stock bridge pup on the G&L Legacy HB, wired to be tapped single coil with a mini-toggle so you can have your standard SSS Strat cake & eat the HSS Strat cake, too. The pup's 4-conductor wiring makes that a snap. It's got slightly stronger bottom & treble ends than an SH-11 Custom Custom (with a bit stronger midrange, less bass and treb than the JB because of the weaker pull of the SH-11's Alnico II mags) which makes it a better Strat mate (IMHO), and using a 250K pot takes some of the glass or brittleness out.
I've sampled the Legacy HB many times over the past few years in the store I frequent, most recently 2 weeks ago, when I acquired via straight-up trade for my '07 MII Washburn Idol WI66PPRO an '08 MIK Schecter Blackjack S-1, the final year they made that particular version of the S-1, sporting a 'Fender' 25.5" Scale like the Legacy, or my '81 STRATand G&L ASAT, vs. the 'Gibson' 24.75" scale of the Idol'. The Idol has/had the Custom Custom, that I'd had rewired to tap the pups via push-pull tone pots, paired with a Duncan SH-1 59 at the neck. The Schecter's stock combo is the JB with the 59, both Alnico V bar mag pups, matching magnetic field strength (thus more even in volume output), wired with a push-pull master tone pot to tap them both to single coil. I much preferred the smoother, cleaner trebs & mids of the JB in either HB or SC mode over the Custom Custom, even though the Alnico II mags of the Custom Custom make it a bit less hot, considering it to be more versatile for my styles.
Either one of them, the SH-4/TB-4 or SH-11/TB-11 (for Strat) would mate well on an HSS Strat. If you want more midrange edge or dirt in your bridge tone w/o a dirt pedal, go TB-11. If you use a pedal or 2 to get the edge, then the TB-4 will offer you more versatility.
