Was musing how Skywatcher produce a 9x50 finder that is not correct image.

Advantages would be it matches the diagonals most of us use, but also the optics should be superior with higher transmission.
This is because no Amici prism would be required.
isadvantage would be difficulty reading star charts etc.
Anyone experienced the pros and cons?
