My Wetzlar is the small one, according to the blades it will handle up to a 9"x11" enlargement. The original baseboard on the Valoy 2 isn't exactly measured by acreage! My reason for switching to the Wetzlar is that the paper I use, DW Kentmere, was a PITA get into the Ganz and my current set up dosen't allow the room to use my beloved 4-blade Saunders (the big one!)
