For bright, glassy vintage tone and the big, full bass response of vintage 50's & 60's Strat pickups go with alnico 5 SSL-1's for the neck and middle and a 59B Trembucker for the bridge.
For a warmer, sweeter, chunkier tone go for alnico 2 Antiquity Texas Hots ( or APS1's ) for the neck and middle and I'd still say a 59 Trembucker for the bridge pickup.
