The best CS never makes up for unpredictable reliability and poor QC. I’ve probably bought my last lupy after having a 15 or so. I’ve had bad luck lately. Today, for the money of vx3s, I’d rather go Nikon, Zeiss or Meopta. I still run 4 var-x3s. If I could find a half dozen like new vari-x3s, I’d grab them even though their coatings are a couple decades old. They were simply bright enough and always predictable.
