I need help in finding a replacement racquet for my girlfriend, since her frame is starting to get old and may not survive another restringing. It is currently a Wilson Hammer 4.0 (head heavy of course), Stretch (so the 28.5 length will be hard to replace), 18x20 stringbed, and 95 sq. in. head size. Pretty unique racquet, so i'm having some troubles finding a good replacement. She likes to hit flat shots and flat serves, and currently enjoys the extra power the hammer and stretch give her, but also likes the control of the 95 and 18x20. I'm currently looking at these choices: Wilson n5 MP Wilson n6 MP Wilson nTour 95 Wilson nTour 105 Wilson nPro Wilson nPro Surge Can you help me narrow this list to 2 or 3 that she should demo? or have any other suggestions from other brands or even from wilson (shark?)?
