You are correct that per saltire isn't as common in the SCA as other divisions. The only restriction on per saltire is it can't mix things that share the same base like argent and ermine.

SENA A.3.B.3.c. Elements Divided Quarterly or Per Saltire: Elements divided quarterly or per saltire may use any two tinctures or furs, as long as they do not share a base tincture. 

What you have is field primary armory - it has no primary charge group. It is automatically clear of any armory that has a primary charge group.

SENA A.5.E.1. Adding or Removing the Primary Charge Group: A new submission does not conflict with any protected armory if it adds a primary charge group or removes a primary charge group.  Thus, any armory which is field-primary does not conflict with any armory which has a primary charge group.
For example, Per bend azure and Or, a clarion and a trefoil counterchanged, a chief indented argent does not conflict with Per bend azure and Or, a chief indented argent, because it adds a primary charge group of the clarion and the trefoil.  For example, Counter-ermine, a bordure argent pellety does not conflict with Counter-ermine, three lozenges argent, a bordure argent pellety, because it removes the primary charge group of the lozenges.

You check it against items in Field Only (which have no charges)
http://oanda.sca.org/oanda_desc.cgi?p=FO

and items in Peripheral Only (has only a peripheral ordinary)
http://oanda.sca.org/oanda_desc.cgi?p=PO

If it's clear in both of those categories then it's clear.

The rules of conflict for this type of armory are just different enough to confuse people.
