Pentax A 45 or Mamiya 45 seckor c ?

After reading Keith's excellent article on a new tilt-shift adapter, I'm curious on the best, affordable, lens choice (https://www.dpreview.com/forums/thread/4461506 and https://www.dpreview.com/forums/thread/4461330 )

This is new territory to me. A cursory check on a variety of used 645 sites suggests to me that the most likely lens candidates would be a Pentax A 45mm or a Mamiya 45 Sekor C. The costs are roughly equivalent.

The Fotodiox adapter comes with several mount types, so I need to choose which one as I don't have any 645 variant lenses on the shelf.

When I check for  reviews, I find differing positions.

Wins over Pentax

Thanks for any shared experience !
