I guess after stringing almost a decade it had to happen and thank goodness it was my personal racquet and not a friend's or worse my wife's. I was supposed to play at 8 this morning but I was wide awake at 5:30 so after frittering away some hours on the computer I thought I'd restring the trusty Head Microgel Radical OS which is an 18 x 19 pattern before heading to the courts. I should say that usually it is 18 x 19 but mine today is 18 x 18 because I took so much time stringing and didn't want to be late to play that I missed weaving that last cross before I tied off. I've been stringing Signum Pro Tornado on my last several restringings using this super slow stringing/clamping method I read about and the time just got away from me. I noticed the missing cross in the warmup but the racquet, my only one, played about like usual and my partner and I won 2 of 3 tough sets. Assuming the racquet plays ok is there any other concern about not playing with a full compliment of crosses? Any danger of damaging the racquet?
