String Help!!

[I love rug]

I've heard of people using two different strings, one for main and the other for crosses. Is it that much better than just one string for both? And which strings would be the best for me:
I am using Head Synthetic Gut PPS 16 and have good power on groundstrokes but need a little more spin.
Thank You!!

Just use a thinner gauge of what you're used to, to begin with.
