I don't quite like the racquet stock. I have been playing with 95 and 98 head sizes the last few years (Head Speed Pro, Wilson 95s). Trying the OS for the larger sweet spot and flex. I'm currently experimenting with lead at 12 and weight in the handle. Looking for more plow through and solid feel. I want to make this racquet work. Any other things I could do? Good string options? Is the control out the window with the 107 head size? I have played 12oz+ sticks so I like heavier frames. Thanks!
