Last couple of weeks Surfa's has been out of pizza flour, so I've been baking with the next best thing: Ralph's Bead Flour. At $2.99 for 5 pounds, you can't beat the price. True, it doesn't have the elasticity and extendability of the Giusto's flour that I prefer, but it's much better than any other brand-name bread flour I've ever tried.
It seems that crusts made with the Ralph's flour benefit from extra-long, retarded ferments. My latest batch was (accidentally on purpose) refrigerated overnight due to a last minute baking-related schedule change. It also seems to handle heavy toppings very well.
Give it a try if you can.
