Hit at lunchtime with Wilson Natural Gut 16 / 4G 125 at 49/45 in a modified Pure Storm GT (16x20, 98").
Wow!!! Extremely comfortable and great combination of control, power, and spin. I used the Wilson since I happened to have an extra half-set laying around. Next time I'll be giving VS Touch/4G a try at this lower tension. The 4G seems stiff enough to provide plenty of control in spite of the low tension, even with gut mains.
