Could someone compare the MX JJS and the N80? How different are they? And how do they perform in comparison to N55? Please also state if you're using MX JJS in 3U or 4U version. I'm not sure if the MX JJS in 3U could be too heavy for singles. I'm also not sure if N80 got enough oomph for singles since its rather an aerodynamic racket than a bulky racket like N55. Comments based on own experience are very appreciated
