220 Film in a Sinar Vario/Zoom

To anyone who has or has used these backs - are they considered "special equipment" where when I load a roll of 220, I would use the dashed start line? Or is it like most other medium format RFBs where the normal solid double-arrowed start mark is appropriate? Thanks in advance!

There is no specific remarks according 220 format in Sinar Vario/Zoom instruction manual.
Solid double arrow is appropriate.


I’m using Sinar Vario and Zoom2, however never had a chance to get 220 film at good price, no experience here with this format
