So I've been stringing on my p200 prince and noticed a couple things. After measuring the mains with string meter, the tension of the center two mains are about 5-10 lbs off reference tension. I've also noticed on my old gamma x2. This can't be normal right? I'm careful to detect any slippage by using dry erase marker on the strings and noticed none. So is it the machine? Second, I string my crosses about 2lbs looser because I heard that helps the poly mains snap back. However with vokl cyclone and tour bite, I did not get this effect. I strung them in low 50s. How can I get this effect?
