I'm stringing a racquet for a friend of mine. She hits with a Pure Drive, played in college, has relatively flat strokes, is accurate and can hit sharp angles and has excellent volleys. The only non-polys I have are Gosen OG Micro, 1/2 set of Alpha Gut and another 1/2 set of Alpha multi. Is there a combination with 2 of those 3 that would work well or is there another string that you would recommend? Also, what tension do you think would be best?
