Deb,
You seem on the up-and-up to me. You have had every opportunity to embellish and make hard sales pitches, but have refrained.
While I can not vouch for your methodology, I'm certain you guys have worked hard to develop it. I'm certain it works repeatably if your recommendations are adhered to. I have long heard that GG's have some unique traits, so they probably can not be compared quite 1:1 to standard BG. The high level of maintenance and fish mixture is not everyone's cup of tea, but that does not make it "wrong".
I will keep looking at GG's open mindedly as an option. Good luck.
