Though about something re: swing weight. The difference in weight between a racquet fully strung with syn gut and full poly is roughly 6-7 grams. Thats a pretty large difference when it comes to swingweight. When you guys measure swingweight do you use full poly, are the strings the same..etc? Just interested in that variable and if you think it matters in nailing SW accuracy for your posted specs. I know in the past when I went to full poly, the racquet swung noticeably heavier and it took a few minutes to get used to. I am guessing the variable could be as much as 6-10 SW points.
