Just fell in love with my new mains: Signum Pro Poly Megaforce 17L (1.19). Could not be happier. Currently using it with Gosen OG Sheep. I'm not a breaker of strings but hit the ball pretty aggressively. I'm wondering what most of you use in your crosses. I'd like to find something a little more livelier than the OG Sheep. Any input would be appreciated.
