Do you know if the VX-IIIs had dual bias springs like the current VX-3s?
Clearly, some folks require more from their scopes than others. Twiddlers and those who tend to bounce them around are going to reveal and/or create more problems than most of us. I'm not a twiddler, and I can even tolerate some uncertainty in the adjustments as long as once sighted, they stay put.
The only rides my scopes get are in a case in my car or in my hands. I can't even spell ATV.
