Looking for recommendations for this dense (18x20) pattern racquet. I currently have one set up with Technifiber X-1 Biphase @ 50 lbs. Next time I would probably string at a little higher, like 52. Has anyone found a good combination? I'm open to Poly, Syn Gut, Multi full beds or hybrids. I'm a high 3.5 or low 4.0. I hit fairly hard and flat off both wings and I'm always looking for an opportunity to come to the net to finish the point.
