Many!
1. Duncan SSL-1 neck and middle...bright, bubbly, 50's like and very Clapton-esque in a Layla sort of way...with maybe a JB JR., Little Screamin' Demon, Hot Rails or Little 59 for hotter, paf-ish (sort of...) bridge pickup tone for soloing. The SSL-1's are about 5% stronger than most 50's Strat pickups...maybe a little more "bark" to the mids but still that great Dire Straits glassy chime.
2. Duncan APS-1 neck and middle (like Jeff Beck has used!) and Twangbanger bridge (for a Tele-esque tone).
3. Duncan Antiquity Texas Hot neck and middle and Antiquity Custom bridge for anything from SRV to Dire Straits...maybe 5% more output than vintage 50's Strat pickups and maybe 5% thicker, smoother, chunkier and warmer than vintage. GREAT VIBE! My personal favorites.
Those are my three favorite Duncan sets for the Strat.
