I played 2 sets of singles with the prestretched X1 last night. The good news to report is that the tension loss according to RacquetTune is that it only went from 7.1% tension loss to 7.7% which is quite impressive. The bad news is that it does not feel like the X1 without the prestretch. That free almost gut like power on demand is nowhere to be found. It still plays pretty well especially on touch shots and still produces some of the best spin of any of the multis.
Tennis is cruel. Just as my tennis elbow went away, I got a wrist injury. Then when the wrist healed, on 1 shot last week my TE came back and is worse than ever. Time to hang up the rackets for a few weeks.
