With a 9.5" radius, you could go either flat profile or vintage stagger - I think the Sinner comes standard with flat profile magnets, so I'd probably stick with that.
Is your Strat an American series, or a pre-2000 American Standard series? Americans have parchment parts, American Standards have white. Unless it's a Deluxe or something.
Am I right that you have Noiseless pickups in neck and middle? In that case it'll make no difference if you have stock or RW/RP wiring for the bridge - you won't get hum-cancelling in the bridge+middle position. Might as well go stock.
