[Elecraft] Question for Optivisor users

[Mike]

I know there are at least a couple of Optivisor users on the list.  I wonder which number visor plates you're using for SMD work?  I just bought a visor with a #3 plate.  I preferred the magnification level of a #4 or #5, but the focal distance was so short with them they seemed to defeat the purpose; I'm 46 and can still see tiny parts pretty well if I get up a couple of inches from them, which I had to do with a #4 plate in order to have it be in focus.  I also got an Optiloupe for it but haven't tried it yet.  Just wondering if anyone has any wisdom to share.  Thank you.
