Dave Swift is using at the moment the standard Super J set of strings on the B, E & A, and using DR sunbeams (45 & 65) on the D & G and this is working out extremely well so far for him. He likes the clarity, precision & bite from the stainless Steels on the lower strings, and in turn likes the softness in feel, the smoother sound and thicker gauge (at least from the D string) of the DR Sunbeams.
If I owned a Super P I would try .130 .105 .90 .70 .50 all non tapered nickel.
