Sorry, I can't offer any info....I'm right there with you. Trying to find a food that works for Zhoie. I have went through several premium brands, but still have yet to find one the relieves the watery eyes.
I too want to try Orjen or Acana...I undestand it is the top of the line in premium foods. I want to get my girl off corn and grains, to see if that helps.
I leaning towards Acana just because of lower protein factors.
I'll watch this post to see the response to you.
