Shades and Greater Shadow Evocation

I'm playing a Sorcerer, so both of these spells are appealing to me for their versatility. I just have one question, if you cast Shades to mimic a Conjuration spell are all save DCs (e.g. Will to disbelieve and/or Reflex if the mimicked spell allows it) for a 6th level spell? Greater Shadow Evocation explicitly says so, but not Shades. Comments?

It's a 6th level spell. Even if you are mimicking a lower level spell it remains a 6th level spell. IMO the save DCs are as for a 6th level spell.
