Yes, Caviar has better pocketing feel for me, but if you don't like the color, then my suggestion for a PSVS string with great pocketing, feel, and performance is razor code white, 18 gauge.
As for the color, I think that's personal preference. To me, the neon red of toro toro looks terrific in that paintjob, but so do carbon-color strings, and white ones (like the aforementioned razor code). Just my style, I don't like blue, green, or yellow strings in a red/gunmetal frame. The best contrasting color in it is white just because of those white accents on the hoop.
EDIT: And as per my sig, I use FireWire Boost not just for the performance and tension maintenance, which is terrific, but the color of it is red & white, so it matches great. Miles of style.
