Hello Guys, during a tournament someone has stolen my spare MX80. Now I'm not sure to buy another MX80 or trying the MX JJS. What are the differences? I know that the MX JJS is less stiff but I had not the possibility to try one because it's not available in Germany. I play 80% doubles and 20% singles. I love the MX80 but I'm looking for an upgrade. Here are my questions: 1. Is the MX JJS headheavier? 2. Is the MX JJS overall heavier? 3. Is the flex close to the MX70? Smash power is important. My defense is good so I didn't need a 4U. Thanks for your help.
