Peter, I see you already have a Crawler, that does perform very good in strats.
For a HSS-setup I would think along the lines of:
Crawler+Irish Tours (splitted you have Fender-quack on the fourth position)
Abraxas+Irish Tours (Abraxas has a little less mids and a bit more topend chime compared to the Crawler)
Holy Diver+Irish Tours (HD sounds more modern compared to Crawler, suitable if you play hardrock, old school or prog. metal)
For SSS:
Irish Tours with a baseplate on the bridge for vintagehot tones.
Slowhands if you want more mids and less chime.
Of course there are other options. That depends on what is most important for you.
