Thanks, Hans. I think I enjoy experimenting even more than playing, given that my playing abilities have never progressed past the mediocre phase... It's probably why I am so fond of the '80s -- tons of design experiments that looked funky and promising on paper, but which turned out to be less revolutionary Wunderwaffe than mediocre dead-end on the court. I (and they) play an essential role in tennis evolution, namely by allowing those who know what they are doing with a racquet to look good through comparative contrast
Before I secured my victim to the Serrano, I sketched out more than a half dozen patterns on paper and picked the one that looked the most promising. The rest were way worse!
