After watching Irvin's videos I strung my first wood racket today, an old Pancho Gonzales Tournament, at 50lbs with Kirschbaum Syn Gut. Then I went to look at the mint Davis Imperial I received today via the auction site. I figured I had better look at the string pattern before I cut out the strings. Then I said WTF? Look at the knots and how many. 8 knots of all shapes and types. Geez, couldn't do anything but laugh. Even I never strung up a racket that bad.
